Joker (The Killing Joke Movie)

The Joker has been a constant nemesis of the Batman, although his past is so shrouded in mystery, even he isn't sure of what he was before he became the Joker. In what was revealed in the movie, the Joker was supposedly a failed comedian who tried to get a performance gig so that he could support his pregnant wife Jeannie while living in a dilapidated apartment building. Out of desperation, he came into contact with two criminals who were planning a heist of the playing card company that was next to the chemical plant where he once worked, and for his help, they would provide him with anonymity by having him wear the mask and cape of the Red Hood, a criminal alias used by others before him.
