You know how some actors are compared to other actors? Well, here's a list of some comparisons that I know (and a few I made up):
Tom Hanks/Jimmy Stewart
How are they similar? Both are well-known for playing the likeable lead in their movies.
George Clooney/Cary Grant
How are they similar? Both are charming and sophisticated men. And oh so sexy.
Robert De Niro/Marlon Brando
How are they similar? Both are well-known for taking their roles seriously. And collaborations with two famed directors (Brando with Kazan, De Niro with Scorsese) doesn't hurt either.
Jim Carrey/Peter Sellers
How are they similar? Both are very versatile in playing multiple roles. Also they can do comedy AND drama with much success.
Meryl Streep/Katharine Hepburn
How are they similar? Really? I gotta explain this? All right, all right. Both are very talented actresses (Hepburn holds the record for most wins by an actor, Streep holds the record for most nominations by an actor). Ironic that Hepburn claimed to have despised Streep (I think she's jealous).
Oliver Stone/Otto Preminger
How are they similar? Both directed critically acclaimed but highly controversial movies.
Heath Ledger/James Dean
How are they similar? Both were very skilled actors who checked out too soon.
Steven Spielberg/Orson Welles
How are they similar? Both rose to fame at a young age and have enjoyed success since.
Quentin Tarantino/Sam Peckinpah
How are they similar? Both have directed movies that glorify violence. Ironic since both of them are very much against it.
Christopher Nolan/Francis Ford Coppola
How are they similar? They had a string of successful films, both commercially and critically. Those films later went on to be their best-known works. For Nolan, they were Batman Begins, The Prestige and The Dark Knight; for Coppola, they were The Godfather, The Conversation, The Godfather Part II and Apocalypse Now.
Clint Eastwood/John Wayne
How are they similar? Mostly renowned for acting in Westerns, they frequently play characters that don't take shit from anyone.
Brad Pitt and Angelina Jolie/Richard Burton and Elizabeth Taylor
How are they similar? They're the most famous couples in Hollywood.
So let me hear what you have to say about this list. Any you want to add? One you want to change? I'm all ears.
