Mine are
1. Tom Hanks: An actor who has avoided being typecast in roles, but no matter what kind of role, he blows you away, eg Saving Private Ryan, Philadelphia...and I'm sure Da Vinci Code will do so too!
2. Ron Rifkin: Not only is Ron the only person who could EVER play Arvin Sloane, he is a fine actor who is very talented.
3. Victor Garber: Victor is just soo cool as Jack Bristow, like with Ron and Sloane, I cant imagine anyone else as SpyDad, awesome!
4. Matt Damon: Loved him in Dogma, Saving Private Ryan, Good Will Hunting...and he surprised me a bit in the Bourne Identity & Supremacy.
5. I am including Sean Connery simply because of the fact he was THE James Bond!
and for the ladies
1. Jennifer Garner: a no brainer, Jen has blown me away as Sydney Bristow in these last 4 seasons (only caught 2 or 3 in season 5), and surely cant be long till till this gorgeous actress lands an Emmy or whatever
2. Meryl Streep: Meryl earns her place in this list purely for her performance in the Manchurian Candidate, awesome as Elenor Prentiss Shaw!
3. Hilary Swank: Loved her in The Core and Million Dollar Baby, very talented lass!
4. Lena Olin: SpyMom had to make it on my list, Lena Olin made season 2 awesome in my eyes, Irina is a fantastic character!
5. Julia Stiles: Enjoyed her in the Bourne Films, talented young lady, not to mention very cute too!
