Bert I. Gordon had a thing for giants. It was his signature. If you were an actor working in Hollywood in the late 1950s and you weren't particularly tall, "Mr. B.I.G." could still make you look sixty feet high with some clever rear-projection and a lot of patience. When people talk about the War of the Colossal Beast cast, they usually start with the man behind the mask, but the ensemble surrounding that radioactive giant is what actually keeps the 1958 sequel from falling apart.
Honestly, it’s a weird movie. It's a direct sequel to The Amazing Colossal Man, yet it feels like its own strange, disjointed fever dream. Most of the original cast didn't come back. That creates this jarring disconnect for fans of the first film. Why did Glenn Manning change so much? Why does he look like a melted candle? The answers lie in the production's shoe-string budget and the revolving door of character actors who populated the American International Pictures (AIP) universe.
Dean Parkin and the Burden of the Mask
Let's get the big guy out of the way first. Dean Parkin stepped into the role of Glenn Manning, replacing Glenn Langan from the first film. It’s a thankless job. While Langan got to show his face and act out the psychological horror of growing too large for his own heart to support, Parkin was buried under heavy prosthetic makeup.
He's basically playing a different character. The Manning we see here is mindless. He’s a beast. Parkin had to convey everything through grunts and lumbering physical movements. Interestingly, Parkin wasn't just some random guy off the street; he worked with Gordon again in The Cyclops. He had a knack for playing these misunderstood, hulking figures. His performance is more about physical endurance than Shakespearean dialogue. Imagine sitting in a makeup chair for hours just to go stand in front of a green screen and swing your arms at nothing. That was Parkin's reality.
The makeup itself is the real star here. Jack H. Young, a legendary makeup artist who worked on everything from The Wizard of Oz to 300, created the disfigured look for Manning. Because Manning supposedly survived a fall from the Boulder Dam, his face is a ruin of scar tissue, with one eye permanently fixed in a wide, terrifying stare. Parkin had to act "through" that single eye.
Sally Fraser: The Emotional Anchor
If Parkin is the monster, Sally Fraser is the heart. She plays Joyce Manning, Glenn's sister. Now, this is a bit of a retcon. In the first movie, we were all about the fiancée. Suddenly, we have a sister who is convinced her brother survived the plunge into the Colorado River.

Fraser was a staple of 1950s sci-fi. You might recognize her from It Conquered the World or Earth vs. the Spider. She had this specific ability to look genuinely concerned about a guy in a rubber suit or a giant puppet. In the War of the Colossal Beast cast, she’s the one doing the heavy lifting emotionally. She isn't just a damsel; she's the catalyst for the entire plot. She pushes the military to look for her brother when they'd rather just forget the whole "giant man" embarrassment ever happened.
Her performance is earnest. In a movie where a giant man steals a bread truck, you need someone to look at the situation with total sincerity. Fraser does that. She treats the "Colossal Beast" as a tragic family member rather than a cinematic gimmick.
The Military and the Scientists
You can’t have a 50s monster flick without some guys in suits and uniforms standing around a map. Roger Pace plays Major Mark Baird. He’s the romantic interest/military liaison. Pace didn't have a massive career after this—his filmography is pretty lean—but he fits the "Standard 1950s Hero" archetype perfectly. Square jaw, authoritative voice, slightly stiff.
Then you have Russ Bender as Dr. Carmichael. Bender was a workhorse. The guy has over 100 credits to his name. He was in Panic in Year Zero! and The Ghost of Dragstrip Hollow. He brings a level of "seen-it-all" professionalism to the cast. When Carmichael explains the science of why a giant man is eating cattle in Mexico, you almost believe him because Bender delivers the lines with such flat, Midwestern authority.
The Supporting Players
- Charles Stewart as Captain Harris: Another reliable character actor who popped up in TV shows like Perry Mason and Alfred Hitchcock Presents.
- George Becwar as John Swanson: He provides the bureaucratic friction necessary to keep the plot moving.
- Roy Gordon as the Mayor: No relation to the director, but a familiar face in "B" cinema.
Why the Recasting Happened
It’s the question everyone asks: Where was Glenn Langan? Usually, in the world of 1950s independent cinema, the answer is "money" or "scheduling." AIP was notorious for moving fast. They didn't want to wait for actors to become available. If they had a window to shoot, they shot.

The change in the War of the Colossal Beast cast actually works in a meta-narrative sense. The character of Glenn Manning is supposed to be unrecognizable. He’s been through trauma, radiation, and a catastrophic fall. By switching actors and dousing the newcomer in liquid latex, Bert I. Gordon leaned into the idea that the "man" was gone, leaving only the "beast."
The Mystery Science Theater 3000 Effect
We can't talk about this cast without acknowledging why most people know this movie today. War of the Colossal Beast was featured in Season 3 of MST3K. The riffing focused heavily on the acting—specifically the "bread truck" sequence and the bizarrely long periods of Manning just wandering around Mexico.
While the MST3K guys poked fun at the performances, it actually preserved the legacy of these actors. Without that show, Roger Pace or Sally Fraser might have been forgotten by all but the most hardcore cinephiles. Instead, their faces are burned into the brains of cult movie fans everywhere. They represent a specific era of Hollywood where "making it" meant getting a lead role in a drive-in movie that would eventually play on UHF stations at 2:00 AM.
Production Reality vs. On-Screen Grandeur
Working on this film wasn't glamorous. Most of the scenes involving the giant were shot using a process called "static matte." This meant the actors—the humans—would film their scenes, and then Dean Parkin would be filmed separately on a minimalist set.
The actors often had to scream at empty air or look at a piece of tape on a wall to represent the sixty-foot threat. This requires a specific kind of talent. It’s not "Method," but it is technical. Sally Fraser, in particular, was a pro at this. Her ability to maintain eye contact with a giant that wasn't there is what makes the forced perspective work at all.

The Tragic Arc of Glenn Manning
The movie ends with a surprisingly dark moment. Manning regains a shred of his humanity, realizes what he’s become, and chooses to end his own life by walking into high-voltage power lines. It’s a bit grim for a movie that features a giant man throwing a bus.
This ending required Parkin to transition from a mindless animal back to a sympathetic human in a matter of seconds. For a low-budget sequel, that’s a big ask. The "Beast" screams "Joyce!"—his sister's name—and for a second, the makeup doesn't look like a mask. It looks like a face. That’s the peak of the film’s acting, and it’s a testament to the cast trying to find depth in a script that was mostly about spectacle.
Actionable Insights for Cult Film Fans
If you’re diving into the world of 1950s creature features or researching the War of the Colossal Beast cast, there are a few things you should do to get the full experience:
- Watch the Prequel First: To appreciate the recasting of Glenn Manning, watch The Amazing Colossal Man (1957). See how Glenn Langan played the role versus Dean Parkin. The shift in tone is massive.
- Look for the Color Shift: The last few minutes of War of the Colossal Beast famously switch from black-and-white to "shimmering" color for the final explosion. Pay attention to how the makeup looks in color versus the grainier B&W footage.
- Track the "Gordon Regulars": Bert I. Gordon used a rotating stable of actors. If you like Sally Fraser, check out Earth vs. the Spider. You’ll start to see how these actors formed a sort of "indie repertory theater" for giant monster movies.
- Check the Credits for Jack H. Young: If you’re a makeup buff, look up Young’s other work. His ability to create a "half-gone" face on a budget is a masterclass in practical effects.
- Acknowledge the Stunt Work: While uncredited, the people who had to "fall" or be "thrown" by the giant were often local extras or low-paid stuntmen. Their reactions sell the scale better than the special effects do.
The legacy of the War of the Colossal Beast cast isn't found in Oscar nominations or box office records. It’s found in the DNA of modern sci-fi. Every time you see a giant monster movie today, you're seeing the evolution of the techniques these actors pioneered while standing in a dirt lot in Griffith Park, screaming at nothing.
