I Am Sam director Jessie Nelson has recalled how Ben Stiller apparently warned her and actor Sean Penn that he was including a joke about the film in his own movie, Tropic Thunder.
Ask Sean Penn, 2001, I Am Sam.
In a new interview with The Hollywood Reporter, Nelson said she remembered Penn receiving a heads-up from Stiller that the joke was included in the film.
The 2008 action film took several swipes at Hollywood, including self-serious method actors and money-spinning franchises.
