Benjamin Edward Meara Stiller was born on November 30, 1965 in New York City. His father, comedian and actor Jerry Stiller, is from a Jewish family that emigrated from Poland and Galicia in Central Europe. His mother, actress and comedian Anne Meara, who was from an Irish Catholic background, converted to Reform Judaism after marrying his father. While the family was "never very religious", they celebrated both Hanukkah and Christmas, and Stiller had a Bar Mitzvah.

When he was approximately 15, Stiller obtained a small part with one line on the television soap opera Guiding Light, although in an interview he characterized his performance as poor. He was later cast in a role in the 1986 Broadway revival of John Guare's The House of Blue Leaves, alongside John Mahoney; the production would garner four Tony Awards.  During its run, Stiller produced a satirical mockumentary whose principal was fellow actor Mahoney. His comedic work was well received by the cast and crew of the play, and he followed up with a 10-minute short called The Hustler of Money, a parody of the Martin Scorsese film The Color of Money. The film featured him in a send-up of Tom Cruise's character and Mahoney in the Paul Newman role, only this time as a bowling hustler instead of a pool shark. The short got the attention of Saturday Night Live, which aired it in 1987, and two years later offered him a spot as a writer.  In the meantime, he had a bit role in Steven Spielberg's Empire of the Sun.  In 1989, Stiller wrote and appeared on Saturday Night Live as a featured performer. However, since the show did not want him to make more short films, he left after four episodes. He then put together Elvis Stories, a short film about a fictitious tabloid focused on recent sightings of Elvis Presley. The film starred friends and co-stars John Cusack, Jeremy Piven, Mike Myers, Andy Dick, and Jeff Kahn. The film was considered a success, and led him to develop the short film Going Back to Brooklyn for MTV; it was a music video starring comedian Colin Quinn that parodied LL Cool J's recent hit "Going Back to Cali".Answer this question using a quote from the following article:
