Some trivia about the movie Funny People:
Leslie Mann plays mother to her real-life daughters (with director Judd Apatow) Maude Apatow and Iris Apatow, just as she did in Knocked Up (2007).
In Knocked Up (2007), there is a scene where the guys are sitting around talking about that, if they "got laid", it was because of Eric Bana in Munich (2005). Bana also stars in this film, and coincidentally (or perhaps not) the director of photography on both Munich (2005) and this film is Janusz Kaminski. Barry Mendel, one of the producers of Munich (2005), is also a producer on this film as well.
The characters of George and Ira were written specifically for 'Adam Sandler' and Seth Rogen.
George and Ira are named after the composer/lyricist brothers George and Ira Gershwin.
