Do you think a prequel would be cool?
Even though this movie really stands on its own and doesn't require a sequel since the meaning of the ending, do you think a prequel would work?
Maybe include some of the mental hospital situations without ruining (instead maybe even expanding) the mystery of Frank's character. and show the start of the Soronprfbs with Scoot McNairy as the keyboard player and more insight on what happened to his character since the start of "Frank". I could see his character have a role of similar importance to how Jon's role was in this film.... It could be titled The Soronprfbs.
I don't know, just a thought. It's probably not likely anyway.
Like I said the movie does stand on its own, but I still would love to see more of Michael Fassbender as Frank and hear some more 'Frank music'. Feel like they could do more with this concept.
