I think its silly they made musicals out of Ghost/Rocky/Spiderman... so why not make one out of the BTTF Trilogy. The music in the movies were iconic, ranging from Huey Lewis, Chuck Barry, to ZZ Top.
Of course a BTTF Musical would also kind of be silly, but I think it would be fun to watch.
Since both Ghost and Rocky were such amazing success stories doesn't that speak for itself as to why Back To The Future should not be made into a musical?
^Ahem, no, it doesn't tell you whether something you have never seen or heard in your life, would be good, bad or indifferent.
Why don't you go? Why don't you leave Manderley? He doesn't need you... he's got his memories. He doesn't love you, he wants to be alone again with her. You've nothing to stay for. You've nothing to live for really, have you?
