Casey appears in the 2007 "TMNT" film, and is voiced by Chris Evans. By the time the film takes place, Casey is now in a relationship with April and he works for her shipping company as a delivery man, spending his nights continuing his vigilante activities. Through this, he meets Raphael as the Nightwatcher, becoming his sidekick - though he claims Raphael is the sidekick. At the beginning of the film, he is the only character to know that Raphael is the Nightwatcher. When he meets Raphael in costume, the latter is at first confused as to how he was able to figure it out, where Casey responds, "Wasn't that hard, man. Y'know, you look like a big metal turtle," and Raphael says, rather despondently, "It's that obvious, huh?"
