ET is on the set of the movie 'Merry Christmas, Drake & Josh,' a film based on the Nickelodeon show "Drake & Josh." We spoke with the movie's stars Drake Bell and Josh Peck to find out how it felt to be reunited as on-screen brothers.

Josh tells ET he is excited about making a big screen version of the show.

"It's totally a trip and surreal," Josh says. "I'm a little older, a little wiser, a little more handsome and a lot more excited to be doing some Drake and Josh magic for kids and family alike."

Josh is also happy about the opportunity to work with his former co-star Drake Bell.

"We've worked together for like eight years and we make each other laugh," Josh tells ET. "He just totally came and was so ready to do this movie, as was I. So we're just kind of laughing and having a great time."

Nickelodeon's "Drake & Josh" revolved around the lives of Drake Parker (Bell) and Josh Nichols (Peck). The two teenagers became stepbrothers after Drake's mom and Josh's father get married.
