Ben Stiller’s character in Little Fockers is actually named Gaylord Focker. “Greg” is the nickname he uses, which is why the character’s formal first name is easy to overlook.
Greg Focker is the central character of the Fockers comedy series. He is married to Pam Byrnes, played by Teri Polo, and repeatedly clashes with her suspicious and controlling father, Jack Byrnes, played by Robert De Niro. The joke surrounding Greg’s name is part of the series’ broader use of awkward family situations and suggestive wordplay.
Little Fockers is the third main film in the series, following Meet the Parents from 2000 and Meet the Fockers from 2004. It was directed by Paul Weitz and released in 2010. The story focuses on Greg and Pam raising twins while Greg tries to prove himself as a capable father and family man.
A common mistake is to answer “Greg,” because that is the name used throughout most of the films. However, the question asks for his actual or formal first name, and the character’s full name is Gaylord “Greg” Focker. The name is also sometimes confused with actor Ben Stiller’s real name, but Gaylord belongs to the fictional character.
