Sawa described his role as "in the beginning, was kinda loopy and cotter, and you know, probably not the most popular guy in school. I think he might have been a dork, you know, doing their stuff and they had their own thing going and they're after the two beautiful girls in school, but there's no chance of that happening. I guess after the plane goes down, his world completely changes". "Devon has an every man quality that makes him accessible," Wong said. "He doesn't appear as if he's supremely self-assured. He's more of a regular kid who can take on the complexities of the role and become a hero". Perry was amazed by Sawa's vulnerability in acting, describing him as "a very distinctive actor. He's very loose and he's kind of a cut-up when he's not on camera, but the moment the camera's on, I'd never seen anybody to completely slide right through the moment".
