Have you ever noticed how some actors always play themselves on the screen?

The worst offenders in my books are, Jack Nicholson (same in interviews as he is on screen) Jim Carey (stuck in rubber face mode ALWAYS), keanu Reeves (Enough said, no Charisma) and Gwyneth Palthrow (Never does power scenes, facial expressions of a dead nit) Whatever the film its a different costume & hair but same person shining through, to me it screams hollywood bake a star-----the ones that cut it for me are truly great like of Meryl Streep (So Diverse & mesmerizing) helen Mirrem, (Can do any Character) Halle berry, (stunning and talented at the same time) Tom Hanks, (funny but can deliver powerful performances) Julia Roberts (one of the greatest actresses of our time) they make every character completely unlike themselves, whats the worst offenders in your eyes, don't even get me on Jude Law or Cameron Diaz the Grinner.
