5.) Donnie Brasco
Depp plays the title role in this film where he is paired against Al Pacino. Talk about a match made in acting heaven! Donnie Brasco is an undercover FBI agent assigned to infiltrate the mob. Aside from watching Depp and Pacino chew scenery together, the real joy here is the way Depp plays Joe/Donnie with a certain veil. Like he would have to as an undercover agent, you can never really get a sense of what’s going on in his mind, and that shines brightly throughout this film.
