Bounce Balls: the preferred method of superhero travel.

that was........ I have no idea what that was.

Judging by the cars, this as filmed in the 1960's. Someone had a creative itch to scratch.

You were close, 1973! This is, as I read, probably the only SFW bit in the whole movie; it's a clip from a really bad porno I only saw a 3-minute clip of and that Something Weird Video has archived and is selling for a 9.99 download or $10 DVD (no, I'm not buying one).

If you'd like a link to the 3-minute clip I saw, lemme know. You don't see a lot (thankfully!), but it relies on bad acting, an unattractive nude couple trying to film a private porno film, and Bat Pussy (it tingles when someone's shooting a dirty movie in "her" Gotham City) out to stop them and getting involved. Good for a real laff
