Well, they did base a movie on Girls Just Want to Have Fun, but I don’t think it made it to a TV series.
Now that we have Lauper and Goldblum in the same thread, we could also imagine a spinoff of Vibes. As it is about pyramids and ancient civilizations, it would probably be popular among BB readers…
Seriously, though, while I can imagine stretching Time after Time into a TV series, I can’t imagine it working well. Better would be Time Bandits: The Series. It could be like a modern Time Tunnel.
