Most VERSATILE/UNSETTLING CHAMELEON ACTORS & ACTRESSES

Never plays "just the same" but varying roles + great immersion in each....Chameleon-like quality, I/You can't believe these different roles were played by the SAME actor!

Could convinsibly pull of a DUAL ROLE in a project (or Multiple roles even - see Ji Sung In Kill Me Heal Me)

Please DON'T just add your favorite actors, there's a bunch of likable actors but if being honest lack versatility/this chameleon quality. Anyone who doesn't differentiate their various characters from each other enough & plays it the same way or near same way -  WILL BE REMOVED FROM THIS LIST!
