Jedis & Jokers
Speaking of Mark..It's kinda funny..The last three people to voice the Joker in an animated series have played (or voiced) Jedis in Star Wars movies or video games. Mark Hamill ofcourse was Luke.
The actor who voice the Joker in "The Batman" was Kevin Michael Richardson who supplied the voice for Jedi Jolee Bindo in Star Wars: Knights of the Old Republic, along with a few other Jedis for other Star Wars Games.
Jeff Bennett supplies the voice for the Joker in "Batman: The Brave & The Bold) and he was also the voice for Kyle Katarn in two other Star Wars video games.
