It was 2013. The Hunger Games was a juggernaut, Twilight had just wrapped up its sparkly run, and every studio in Hollywood was desperate to find the next young adult goldmine. Enter the cast of City of Bones. On paper, it looked like a slam dunk. You had a massive book series by Cassandra Clare, a gritty urban fantasy setting in New York, and a group of actors who—honestly—looked like they stepped right off a Pinterest fan-casting board.
But then the movie actually came out.
Critics weren't kind. Fans were... divided. Some people absolutely lived for the leather jackets and the runes, while others felt like the chemistry just wasn't hitting the mark. Looking back over a decade later, the way the cast of City of Bones came together tells a fascinating story about the "YA Boom" and why some adaptations catch fire while others just sort of flicker and fade. Lily Collins and Jamie Campbell Bower were the faces of a franchise that was supposed to span six movies. Instead, we got one film, a lot of "what if" scenarios, and an eventual TV reboot that changed everything.
Lily Collins as Clary Fray: The Heart of the Shadow World
Lily Collins was basically born to play Clary Fray. If you look at the cover of City of Bones, the resemblance is eerie. She had that "girl next door but make it supernatural" energy that the role required. When she was cast, she was already a rising star, coming off Mirror Mirror. She understood Clary’s journey from a confused Brooklyn teenager to a demon-slaying Shadowhunter.
The weird thing about Clary's character in the film is how much the script leaned into the "chosen one" trope. Collins played it with a lot of sincerity, but the movie rushed her development. In the books, Clary’s realization that her life is a lie feels heavy and terrifying. In the film, Collins has to move at breakneck speed because the producers were trying to cram an entire world-building manual into two hours.
One thing people forget? Lily Collins actually stayed very close to the source material. She was a fan of the books before she even got the part. That’s why her performance feels grounded even when the CGI around her starts to look a bit dated. She captured that specific brand of teenage stubbornness that makes Clary both endearing and occasionally frustrating.
Jamie Campbell Bower: The Divisive Jace Wayland
Now, if you want to start a fight in a Mortal Instruments fan forum, just mention Jamie Campbell Bower.

Jace Wayland is a difficult character to pin down. He’s arrogant, beautiful, tortured, and highly skilled. He’s the quintessential YA bad boy with a heart of (literal) gold. When Bower was announced as part of the cast of City of Bones, the internet went into a bit of a meltdown. He wasn't the hulking, muscular Jace some readers imagined. He was lithe, angular, and had this almost ethereal, rock-star vibe.
It worked. Sorta.
Bower brought a sharp, biting wit to the role that Jace desperately needed. His chemistry with Lily Collins was undeniable—mostly because they actually ended up dating in real life during production. That "lightning in a bottle" romance gave their scenes a tension that felt real. You could tell they weren't just reciting lines about angelic blood and ancient curses. They were actually into each other. But for some fans, Bower was "too skinny" or "too edgy." Looking back, his performance is actually one of the highlights of the movie. He leaned into the arrogance perfectly.
The Supporting Players: From Robert Sheehan to Lena Headey
The real strength of the cast of City of Bones was actually in the fringes.
- Robert Sheehan as Simon Lewis: This was casting genius. Sheehan, fresh off his success in Misfits, played the "friend-zoned" best friend with so much heart. He was funny, relatable, and the only person in the movie who seemed to realize how ridiculous everything was.
- Kevin Zegers and Jemima West: As Alec and Isabelle Lightwood, they had the "cool older siblings" vibe down to a science. Zegers, in particular, had the tough job of portraying Alec’s repressed feelings and loyalty, though the movie barely scratched the surface of his character arc compared to the books.
- Lena Headey as Jocelyn Fray: Before she was ruining lives in Game of Thrones, Headey was playing the protective, secret-keeping mother of a Shadowhunter. She didn't have much screen time, but she brought a weight to the film that helped it feel like a "real" movie rather than a CW pilot.
- Godfrey Gao as Magnus Bane: We have to talk about Magnus. The High Warlock of Brooklyn is a fan favorite, and the late Godfrey Gao looked incredible in the role. The eyeliner? Impeccable. The presence? Commanding. The only problem was he was barely in the movie. It felt like a tease for a sequel that never arrived.
Why the Chemistry Didn't Save the Box Office
You can have the best cast in the world, but if the pacing is off, you're in trouble. The cast of City of Bones suffered because the movie tried to be too many things at once. It wanted to be a romance, an action epic, and a mystery. By the time we get to the big twist regarding Valentine Morgenstern (played by a very intense Jonathan Rhys Meyers), the audience was already exhausted.
Jonathan Rhys Meyers is an incredible actor, but his Valentine was... a choice. He played him with this frantic, braid-wearing energy that felt very different from the calculated, cold villain in Cassandra Clare's novels. It’s one of those instances where a great actor maybe leans too hard into the "crazy" and loses the "scary."

The Shadowhunters Legacy: Movie vs. TV Cast
When the movie failed to spawn a sequel, the rights eventually moved to television, leading to the Shadowhunters series on Freeform. This created a permanent divide in the fandom. You had the "Movie Purists" and the "TV Lovers."
Dominic Sherwood took over for Jamie Campbell Bower, and Katherine McNamara took the mantle from Lily Collins. The TV show had more time to breathe—three seasons to tell the story—but many still argue that the cast of City of Bones captured the vibe of the characters better, even if the movie itself was a mess.
There's something about the cinematic scale of the film that the TV show couldn't quite replicate. The costumes in the movie were high-fashion leather; the TV show looked a bit more like a high-end Halloween store at times. But the TV show gave us a much deeper look at the relationship between Magnus and Alec (Malec), which the movie only hinted at with a few lingering glances.
What Went Wrong with the Casting Strategy?
Honestly? Nothing was wrong with the actors. The problem was the timing.
In 2013, the market was over-saturated. Beautiful Creatures and The Host had also recently flopped. Studios were trying to force these actors to be the "next big thing" before the audience had a chance to actually fall in love with them. The cast of City of Bones was marketed as icons before the first frame even hit the screen. That’s a lot of pressure for a group of twenty-somethings.
Also, the movie made some weird changes to the lore that the cast had to just... roll with. Adding the "Portal" in the basement of the library and changing how the runes worked didn't help the actors ground their performances. They were constantly reacting to green screens and convoluted plot points that didn't always make sense even if you had read the books.

Where is the Cast Now?
It’s actually pretty impressive how well the main cast did after the film.
- Lily Collins: She’s a massive star now, primarily known for Emily in Paris and her Oscar-adjacent roles like Mank. She moved far away from the YA genre and carved out a very successful career as a leading lady.
- Jamie Campbell Bower: He’s had a major career resurgence lately. If you watched Stranger Things Season 4, you saw him as Vecna. He’s still got that haunting, intense energy that made him an interesting Jace, but he’s found his niche playing complex villains.
- Robert Sheehan: He became a cult icon as Klaus in The Umbrella Academy. He’s basically perfected the "lovable mess" archetype that he started exploring as Simon.
- Aidan Turner: He played Luke Garroway (the werewolf father figure) and went on to become a household name in the UK with Poldark.
The Unseen Potential of the Franchise
If the movie had been a hit, we would have seen this cast tackle the City of Ashes storyline, which is arguably much darker and more interesting. We would have seen the introduction of Sebastian Morgenstern, more of the Seelie Court, and the actual development of the war between the Clave and Valentine. Instead, the cast of City of Bones remains a "what could have been" moment in cinema history.
The film is a time capsule. It represents a very specific era of filmmaking where everyone was looking for the next Twilight. It’s a movie that is better than people remember but not as good as fans wanted it to be. The actors did the heavy lifting, but the script just couldn't carry the weight of the world Cassandra Clare built.
Final Thoughts for Fans
If you're revisiting the film today, try to look past the dated 2013 aesthetics. Watch it for the performances. There is a charm in the way Lily Collins and Jamie Campbell Bower interact. There is a genuine humor in Robert Sheehan’s delivery. The cast of City of Bones deserved a better script, but they gave it their all regardless.
How to experience the story today:
- Watch the Movie: It’s usually available on major streaming platforms like Netflix or Prime Video depending on your region. It’s worth it for the visuals alone.
- Compare with the Show: Check out Shadowhunters on Hulu or Disney+ to see how different actors interpreted the same roles.
- Read the Books: If you haven't, go back to the source. The nuances of the characters that the movie missed are all there in the prose.
- Check out the Spin-offs: The Shadowhunter Chronicles is massive now. From The Infernal Devices to The Last Hours, the world is much bigger than just Clary and Jace.
The movie might be a standalone oddity now, but it helped cement these characters in the pop culture lexicon. Whether you prefer the film cast or the TV cast, there's no denying that the Shadowhunter world is one of the most resilient fandoms out there. Just don't mention the braids on Valentine's head—some things are better left in 2013.
