darkman (1990)

"What is it about the dark? What secret does it hold?"
Peyton Westlake (Liam Neeson) is a scientist who has discovered a process to make synthetic skin. Unfortunately the skin degrades after 100 minutes in daylight. Then Peyton is attacked by gangsters and is left for dead, horrifically burnt. Once recovered and hideously scared Peyton wants revenge, and he converts into Darkman. Using his synthetic skin he is able to take on the appearance of anyone and is impervious to pain. But he still cannot last longer than 100 minutes in any disguise.
An original comic creation by Raimi has more depth than most, and is thus more interesting, but the complexity of Peyton Westlake and the sadistic pleasure he takes in torturing his victims make him less sympathetic as a character. His motivations point towards the more recent Batman, but at the time was a step to far for most
