In 1999, the boys acted in their first major movie, "Big Daddy". They shared the role of a five-year old boy named 'Julian' who is adopted by Adam Sandler's character, 'Sonny Koufax'. That year, the boys worked with Sandler to make the second and third versions of "The Chanukah Song". The boys also had a small role in the scary movie "The Astronaut's Wife". After "Big Daddy"'s release, the two started a slow period in their careers. They were not cast in any big roles for a time. During the early 2000s, the twins acted in episodes of "The Nightmare Room" and "That '70s Show". They also acted in "MADtv" (season four, episode #425) and the movie "The Master of Disguise." They also had a voice-over role in "Adam Sandler's Eight Crazy Nights". In 2001, Cole started acting in episodes of the television show "Friends" as Ross Geller's son Ben. He did not share this role with Dylan.
