There are some choice quotes in here, to whit:
Justin Long (Brandon, the young fan) [reading a text from his neighbor, Alec Baldwin, when he offered to confirm this rumor]: Yeah. Baldwin says he was offered and then un-offered. Same with “The Godfather,” “Arthur” and “Pride of the Yankees.”
Dean Parisot: …you could never tell whether that was Alan being in character or Alan actually responding to Tim.
Sam Rockwell: Tony played it like a failed Scientologist.
Missi Pyle: People ask me to make the sound a lot. Which I can easily do. The description in the script was “a baby in a bagpipe.”
