6. Tommy Lee Goes Full Jack Nicholson
Burton's Batman movies were full of great villains from top to bottom: even the henchmen were memorable, so it's not at all surprising that Joel Schumacher chose to base both of his Batman Forever villains on Burton's most iconic villain, The Joker. The Riddler is arguably the least obvious of the two, since Jim Carrey brings so much of his usual mugging routine to the character, and it's easy to imagine Edward Nigma as a not-too-distant cousin of The Mask, but in Two Face, we were treated to a Joker clone in different clothing. The direction was clearly designed to such ends, but Tommy Lee Jones' performance draws so heavily on Nicholson's Joker that he fails to bring anything of Two Face to the screen at all, aside from his look and the coin motif. It is a blatant attempt to cash in on the unconscious appeal of the character, but at the same time it meant that Jones was never able to offer his own performance, and the heritage of the character was basically flushed down the toilet.
