I am a fan of Gywneth Paltrow or Martin?
I'll watch any movie she is in. Whenever she is interviewed, like on Inside the Actor's Studio, she seems down to earth and fun. When I am in imitation mode at social gatherings, I mimic her and it works, people respond warmly to me.
Other favorites:
Leo
Dame Judy Dench
Helen Mirren
Least:
I think Usher is a horrible actor, great dancer and singer yes, but actor? Definitely not.
Brittney Spears is annoying, but I do like that Toxic song, however I wouldn't call myself a fan.
Tallgirl.
