I think Gary Oldman picks his roles very carefully, because he doesn’t have a lot of bad movies.
This is one gem, directed by Luc Besson. It’s a great story, but with three amazing performances. Off course Jean Reno and Natalie Portman shine, but Gary Oldman is really creepy and convincing as the villain. Honorable Mentions: “True Romance”, “Dawn of the Planet of the Apes”, “The Fifth Element”, “Harry Potter and the Prisoner of Azkaban”, “Batman Begins”, “Tinker Tailor Soldier Spy”
A very recent movie. And it wasn’t because of him, Oldman was probably the best bit of the film. “Paranoia” just didn’t do it for me. It was boring.
Dishonorable Mentions: “Red Riding Hood”
