Answer: Ben Stiller
Stiller, born on November 30th, 1965 in New York City was cast as Larry Daley. Larry had a son, Nicholas, with his ex-wife, Erica, and they shared custody of him. Larry could not keep a job and kept going from place to place until he finally went to an agency in New York City. The lady said his resume was not the best she had seen but that she knew of a place which would hire Larry. She sent him to the Museum of Natural History and Larry got a job as a security guard during the museum's closing hours. During Larry's late shift, all the artifacts in the museum came to life through a tablet. The first alive artifact that Larry encountered was a T-Rex. The T-Rex chased him and Larry did not know what to do. He called another guard and the guard informed Larry that he had to read the instruction manual. In the manual, it said to throw a bone so the T-Rex could chase it. Larry realized that the T-Rex did not want to hurt him but he just wanted to play fetch. At the end of the movie, a couple of retired guards tried to steal the tablet since they wanted to feel young again but Larry managed to get the tablet back so the artifacts could continue to come to life each night at the museum. Stiller reprised his role of Larry Daley in "Night at the Museum: Battle of the Smithsonian". He was also in the movies, "Zoolander" and "There's Something about Mary".
