Alex Aja Explains the Importance of Using CGI Alligators in ‘Crawl’ [Interview]
There’s one thing you won’t see a lot of in Alexandre Aja’s new man-eating alligator movie Crawl, and that’s real life alligators. Or, for that matter, an abundance of animatronics and puppets. The new thriller, starring Kaya Scodelario as a college student trapped in a house in the middle of a hurricane as it fills with water and angry alligators, relies almost entirely on CGI creatures.
In a new interview with Bloody-Disgusting, Alexandre Aja explained the importance and necessity for CGI creations over practical effects, and revealed that – although computers did a lot of the heavy lifting – there was practical work done on the set to make the illusion convincing.
“There are, I think, four or five shots that are practical, at the end,” Aja explains.
“We had a tail to do some of the movement in the water, we had a head for the head coming out. We had the jaws open when you see [Kaya Scodelario] through the teeth. That’s practical. The baby alligators are also practical.
“The rest was full CG, but it was a decision taken very early on because […] to recreate the movement, the speed, the ferocity of these beasts, there is no animatronics that can achieve that,” Aja says.

Alexandre Aja is, of course, referring to the fact that – as impressive as animatronics have become – the art form has its own limitations.
“I was not missing the animatronics for a simple reason. When you go with animatronics you’re mostly locked into a frame,” Aja says, referring to the need to shoot animatronics from specific angles, to hide the seams and the puppeteers.
“It was good when you were mixing a lot of movies with a lot of […] fast cuts,” Aja adds, but that wasn’t what he had in mind. “I wanted to be around them. I wanted to see their whole body moving towards her and closing on her. I really wanted to feel that they exist within the frame with her, and that’s something that usually animatronics doesn’t let you do because you have to restrict framing a lot.”
Still, no matter how much CGI a film like Crawl uses, for the effects to be believable it takes additional work on the set.
“I’m a big partisan of mixing technology and I was really hands-on, to be sure that we create the place for the visual effect, [so] that we could really incorporate them the best way,” Aja explains.
“So like a diver recreating the wake as it [the alligator] comes out of the water, so we’d have the real movement of the water. From the distant crawling in their spandex green suit through a cable [to] get the right movement on the ground, and on the set around. Those were very important elements,” Aja says.
You’ll get a much closer look at the alligators of Crawl when the film opens in theaters this weekend!

‘Rubberhead’ Director Nick Taylor on FX Maverick Steve Johnson, Practical Effects, and Seven-Year Journey
Horror journalist, producer, and podcast host Nick Taylor moves into the director’s seat for his feature debut with illuminating documentary Rubberhead: The Life & Monsters of Steve Johnson.
It chronicles the wild life and career of SFX maverick Steve Johnson, based on the multi-volume book series Rubberhead: Sex, Drugs and Special FX, and those familiar likely already know Rubberhead isn’t your standard horror documentary.
Johnson is responsible for so many memorable movie monsters, having worked on Fright Night, Poltergeist II, An American Werewolf in London, A Nightmare on Elm Street 4: The Dream Master and Night of the Demons, to name a few. He’s also extremely candid in ways that feel atypical in this industry, open about his failures as much as his successes.
“It was a natural progression for sure,” Nick Taylor tells Bloody Disgusting of his transition into filmmaking ahead of Rubberhead‘s world premiere next week at the Fantasia Film Festival on July 23. “I think with my podcast, I got adept at interviewing people and pulling creative lessons out of them, which was the point of my podcast. I wanted this movie to be sort of a creativity pill for artists where if they’re starting a project or feel creatively stuck, they could watch this movie and be inspired and get actual practical creative lessons.”
Taylor’s background in PR and marketing also organically led him down this path.
He charts the course from book promo to documentary director: “But also Bloody Disgusting had a lot to do with this movie because in the very beginning when I first met Steve, I was helping him promote his book and I said, ‘Hey, I got a marketing background and a journalism background. Let me help you promote this book. I’ll just pitch stories from your life to the media, and we’ll see what happens.’ And John Squires wrote an article about Steve making Slimer under the influence of tons and tons of cocaine, and that went fairly viral.”

“For a week, it was story time with Steve,” Taylor continues. “He would tell me a story from his life, and every story was about a major movie, a major director, lots of drugs and alcohol and insanity. I would write them up, and I think John published about three or four of them. So huge shout out to John Squires because that was really great. So yeah, there were definitely a lot of outgrowths of my journalism background that definitely contributed to this movie.”
Rubberhead condenses the multi-book series into a cohesive feature film with a breezy runtime, sparking the obvious question as to how Taylor approached condensing Johnson’s life down to an under 2-hour documentary film.
“That was one of the more difficult parts of all of this, because we had enough for a series or an epically long six-hour fan documentary,” he answers. “But from day one, I did not want to make a fan documentary. I love them. They’re a lot of fun, but I did want the movie to stand on its own two feet as a character-driven portrait of an artist and a time period and a technology, that being practical effects. I did want to be objective. I didn’t want to make this too long. I wanted to make it re-watchable. So I think we just really had to focus on what the narratives were that we wanted to tell. So there were some basically almost cliché archetypical mythic narratives present in Steve’s life. We could have made this way longer, but we wanted to keep it short. But luckily that’s why you have special features.”

Johnson quickly proves to be an engaging subject thanks to his self-effacing wit and frank self-reflections; expect no shortage of stories about how drugs factored into the height of his career or the failures it wrought.
That rare quality was an asset for Rubberhead, Taylor confirms. “He does not shy away from anything about the drugs, the addiction, the bridges burned, the mistakes made, the lessons learned. He just is honest about all of it. He’s had a lot of time for reflection, and he’s done a lot of reflection, so he doesn’t shy away from any of it, which is huge because it’s very refreshing. I don’t think a lot of people are that way, at least in this industry from what I can see. So I think it was hugely beneficial. We wanted to lean into that, and we wanted to make this sort of a gonzo Hunter S. Thompson sort of wild tale through Steve’s overall life.“
Condensing his life into this doc was a slow and steady process for Taylor, too. “It’s been almost seven years. It’s been a labor of love. We’ve been as indie as it gets. We would shoot what we could when we could, and then we would edit when we could. Then after a while it all came together.”
In a way, making Rubberhead brings Taylor’s horror fandom full circle. It turns out that the very film that sparked his interest in the genre and practical effects also comes with an amusing Steve Johnson anecdote.
Taylor explains, “My gateway for sure was Beetlejuice. I saw that at a very young age; I think I was four or five. I felt somebody had shown me, my soul. I get a little emotional thinking about it. There was something about that movie that felt so strange and unusual, but also felt so familiar. It was spooky, but it was fun, and it was lighthearted, and it had humor, but it also had this macabre celebration to it that I just really got into as a kid. I felt somebody had shown me my own soul. And funny story, Steve got fired from Beetlejuice because Tim Burton gave him his hand-drawn designs and Steve’s like, ‘Oh my God, these look like kids did them. This is not what you want. I know what you want. I’m going to redesign these for you.’ And Tim Burton was like, ‘Yeah, no, you’re not.’ So yeah, funny story.”
