Some of you've probably already seen this. I like it alot, its campy, but cool. Kind of like watching Ash kick deadite ass in Evil Dead.
Background is, Batman is killed, and the new commisioner isn't allowing anyone to investigate his murder. So Dick Grayson puts on his cape again after a long retirement to avenge his mentor. Some great casting, check out the Joker in particular.
So, without further ado, sit down and enjoy the movie trailer titled Grayson.
