Like they're natural.

For male I would say : Noah Wyle
This guy was terrific in ER.

For female: Jennifer Lawrence
I think she has great potential.

can't agree on Jennifer, i good yes but extremly is not my cup of tea

some i like are, Ralph Fiennes, Jeremy Irons, Kevin Spacey, Michael Caine, Gary Oldman, Charliez Theron <3, Hugo Weaving, theese are just a few i Think are really good

not so good but i like anyway, John Goodman, Mark Wahlberg,

Anthony Hopkins

Rita Hayworth
Ingrid Bergman

Best of the best.

Kevin James

Vincent Cassel

my man depp.

fear and loathing in las vegas is a top 3 movie for me.

I agree on JLaw.

Seems like so many people hate her now just because of the shit role they turned Mystique into on Xmen.

Male : Benicio Del Toro
Female : This is premature but I think Margot Robbie is going to have a long great acting career.

alicia vikander when she chooses a legit role

I consider Michael Fassbender as the best male actor working today.
Honorable Mentions: Benicio Del Toro, Garry Oldmen, Tom Cruise and Tom Hardy
For the past probably Klaus Kinski.
On female I agree with Lawrence, she is awesome given the right role.
I also like Scarlett Johansson
