Deadline:

Alec Baldwin is boarding Todd Phillips’ Joker movie at Warner Bros. in a supporting role, Deadline has learned. Cameras role on Sept. 10.

While Warner Bros. has not confirmed what role, buzz is that Baldwin is poised play the role of Thomas Wayne, who in DC canon is Bruce Wayne/Batman’s father. Thomas Wayne was first introduced in Detective Comics #33 (Nov. 1939) and he is respected physician and philanthropist in Gotham City. Wayne and his wife are murdered exiting the theater, an incident which young Bruce witnesses. That becomes his m.o. for ultimately becoming a vigilante. In the early comics, Wayne’s murderer is mugger/hitman Joe Chill, but starting with the first Tim Burton 1989 Batman movie, it’s the Joker who is the culprit.

This movie gets more and more surreal.

Funny thing is, I always thought that Baldwin would make a great Batman.
