The classic gag of the toy bang flag made its appearance in the 1989 Batman movie.
Hopefully someday soon they will make a retro Batman Arkham 1989 nostalgia video game. Imagine if they could put a modern Rocksteady gaming engine on classic 1989 Batman. Flying through Tim Burton's Batman universe with its original soundtrack? Awesome indeed. Then they will have to release an original 1960s TV batman game! Fighting baddies with the TV theme song would so rock!
