Considering what had been done with stunt work in the Douglas Fairbanks' Zorro
films it's fun to imagine what a more serious Batman could have been like back then with the resources of a decent feature film.

In a way it whets my appetite to see a retro Batman film. Something like what was done showing Captain America set in the '40s, which I thought was awesome.
