You know that feeling when you're scrolling through a streaming service and a movie title sounds vaguely familiar, but you can't quite place the faces? That’s exactly the vibe with the Something in the Water cast.
Most people get this mixed up. Seriously. If you search for this title, you’ll find about four different movies with the exact same name. There’s the 2024 shark thriller that just came out, a 2022 drama, and even some documentaries. But when film buffs talk about the "classic" indie version that built a weird, lingering reputation for its raw performances, they are almost always talking about the 2009 Australian production.
It’s a gritty film. It isn't a blockbuster. Honestly, the budget was clearly tight, but the casting is why people still look it up over a decade later. It features actors who weren't necessarily household names globally but were—and are—absolute powerhouses in the Australian film circuit.
The Core Players of the Something in the Water Cast
Let's talk about the leads. The movie centers on a group of friends, and the chemistry has to be believable or the whole "survival" aspect falls apart.
Fiona Maclaine takes on the role of Sarah. She’s the anchor. Maclaine’s performance is interesting because she doesn't play the "final girl" trope in a way that feels scripted. It’s messy. You’ve probably seen her in other niche Australian TV projects, but here, she captures that specific brand of suburban anxiety that the movie relies on.
Then you have Chrystabel Hill Smith, who plays Alex. Alex is often the character that audiences have the strongest reaction to—sometimes she’s relatable, sometimes she’s incredibly frustrating. That’s the sign of good acting, honestly. Smith brings a certain edge that prevents the group from feeling like a monolith. They feel like real, flawed friends.
Vaughan Slinn plays Tom. Slinn is one of those actors who can do a lot with a look. In this film, his role is pivotal because he balances the shifting power dynamics within the group.

And we can't forget Bree Robertson. She plays Maya. Robertson has a background in performance that includes more than just traditional acting—she’s actually an accomplished rhythmic gymnast and contortionist. This physicality translates into her screen presence. She moves differently than the others, which adds a layer of subtle discomfort to the group's predicament.
Why This Specific Cast Worked for a Low-Budget Thriller
Small films live or die by their actors. You don't have CGI. You don't have a $100 million marketing budget. All you have is a camera and some people in the woods or by a lake.
The Something in the Water cast had to do the heavy lifting of making a relatively simple premise feel terrifying. The "something" in the water is often more about the psychological breakdown of the group than it is about a physical monster.
- Naturalism over melodrama: They talk like real people. The dialogue isn't "movie-speak." It’s clipped, sometimes repetitive, and filled with the kind of shorthand friends use.
- Physicality: Because they were filming in actual rural locations, you can see the genuine exhaustion. They aren't "movie-sweaty" with perfectly sprayed-on mist. They look tired.
- The "Who is that?" factor: Using actors who weren't overexposed helped the immersion. You don't see "The guy from that Marvel movie." You just see the character.
Common Misconceptions About the 2024 Version
Now, look. If you came here looking for the 2024 movie directed by Hayley Easton Street, you’re looking at a completely different beast. It’s easy to get them confused. The 2024 Something in the Water cast features Hiftu Quasem, Lauren Lyle, and Natalie Mitson.
That version is more of a traditional "sharks in the water" thriller. It’s got that 47 Meters Down energy.
The 2009 version—the one we’re digging into—is much more of a slow-burn psychological horror. It’s "ozploitation" light. It’s about the environment. It’s about what happens when a group of city people realize they are completely out of their element. If you go into the 2009 film expecting shark jumps, you’re going to be disappointed. But if you want to see a masterclass in building tension with five people and a body of water, it’s the one to watch.

Where Are the Cast Members Now?
It’s been a long time since 2009.
Bree Robertson has continued to work in the industry, often blending her incredible physical skills with acting. She’s a great example of how niche skills can sustain a long career in entertainment. Fiona Maclaine has kept a relatively low profile, which is common for many actors who dominate the indie scene for a season and then move into other creative avenues or regional theater.
Vaughan Slinn has remained active in the New Zealand and Australian arts scene. He’s done voice work, shorts, and theater. This is the reality of the industry for many talented actors in that region—they are "working actors" in the truest sense. They aren't chasing the Hollywood sign; they are doing the work where the stories are being told.
How to Tell the Different "Something in the Water" Movies Apart
Since there are so many, use this quick checklist:
- The 2009 Version: Low budget, Australian/New Zealand vibe, psychological thriller, focus on group dynamics. This is the one featuring Fiona Maclaine and Bree Robertson.
- The 2024 Version: British production, high-stakes wedding trip gone wrong, features sharks. Cast includes Hiftu Quasem and Lauren Lyle.
- The 2022 Version: This is often a documentary or a short drama about environmental issues. If there isn't a sense of impending doom in the first 10 minutes, it's probably this one.
The Legacy of the 2009 Film
Why do we still care about the Something in the Water cast from fifteen-plus years ago?
Part of it is the "lost media" feel of the 2000s indie era. Before everything was instantly available on twenty different streaming apps, movies like this traveled by word of mouth at film festivals. They felt like secrets.

The acting is the reason it isn't forgotten. Usually, in cheap horror, the acting is the first thing people complain about. Here, the performances are actually the strongest part. They managed to elevate a "friends in peril" script into something that feels uncomfortably intimate.
What You Should Do Next
If you’re a fan of survival horror or Australian cinema, tracking down the 2009 version is a solid Saturday night plan. Just make sure you’re looking at the right IMDB page.
Watch for the performances: Pay attention to Bree Robertson’s movement and Fiona Maclaine’s facial expressions during the final act. It’s a lesson in how to act with your eyes when the script gets sparse.
Check out their other work: If you liked the vibe, look into the "Australian New Wave" or modern Ozploitation. There’s a specific grit there that you just don't get in American studio films.
Verify your source: If you're buying a physical copy or a digital rental, double-check the year. You don't want to pay for a shark movie and end up with a psychological indie, or vice versa—though honestly, the 2009 film is the more interesting watch for a true cinephile.
The beauty of the Something in the Water cast is that they remind us that you don't need an A-list name to make a character stick in someone's head for a decade. Sometimes, you just need a good script, a creepy lake, and actors willing to get a little bit dirty.
