It wasn't until 1998 that Walker made his feature film debut in the comedy Meet the Deedles, which finally gained him fame. This subsequently led to supporting roles in the movies Pleasantville, Varsity Blues, She's All That, and The Skulls.

In 2001, Walker's breakthrough role arrived when he starred opposite actor Vin Diesel in the successful action film The Fast and the Furious.

During the filming of Running Scared, director Wayne Kramer stated that, "[Walker] is that guy on some level but he’s not really" when comparing Walker with his character in the movie, Joey Gazelle. Kramer continued on to say that he "loved working with [Walker] because as a director he’s completely supportive of my vision of what the film is. And even better, he’s completely game for it."
