None. Never again.
After one of the best themes ever becoming the worst game ever (GB) and my favorite movie ever becoming a huge scandal & debacle (Lebowski) - I'm completely cleansed of the desire to have my favorite themes as pinball. It's no longer something I crave in my life.
If a game with a theme I liked came out, had finished code, and was actually really really good - I'd consider it then...but never up front, ever.
