*Worth seeking out
MacGuffin Movies 
I keep a list of the FS movies I’ve seen as well. It’s shocking how unavailable some of these are, like Johnny Concho and Come Blow Your Horn. But you still have some easy ones to see. I think Meet Danny Wilson is an interesting little movie. Lots of good songs like All of Me and I’ve Got a Crush on You. The Joker is Wild is another one I’d recommend.
