In an interview with Forbes, actor Robin Williams talked about working with Al Pacino in 2002’s Insomnia, and said “[His] character was crazy. Before every take, he would roar like a lion.”

Roar like a lion. “Roaring,” of course, might be a bit of an extreme characterization — but Pacino certainly isn’t known for his whispering roles.

Chicago-based filmmaker Nelson Carvajal threw together a memorable compilation that is appropriately called “Pacino: Full Roar”  that contained  some of the actor’s most memorable movie meltdowns.
