Actually, SUMMER STOCK would make my top ten,, if for nothing else than Gene Kelly, the newspaper, and the creaky board. I've always loved BRIGADOON specifically for its fake sets. I know Kelly wanted to film this on actual Scottish locations, but I think the reality would have ruined the fantasy element. Mythical Brigadoon should look like a movie set...not any real place. In fact, somewhere in the sixties, they actually did a production of BRIGADOON for TV with Bob Goulet and Peter Falk (in the best friend role) on real locations (I don't remember if they were Scottish locations or not), but it looked all washed out and flat and did not have the ethereal, otherwordly aura of Kelly's Brigadoon. After all, is there anything more fantastical than "better than real life" M-G-M colour?
I'm a big proponent of soundstages myself. I like the way film-makers with imagination can control the look of the film with just sets and good art direction. John Ford's moody IRA thriller, THE INFORMER, was all shot on discard sets. You can also control the budget and the vicissitudes of nature on a soundstage.
WORDS & MUSIC is a good bad musical choice, MattH. Mickey Rooney trying too hard, the bland Tom Drake, and a soppy, messy, tedious story. Without the songs (and I'm not sure they're given the best forum), this is a dreary mess. TILL CLOUDS ROLL BY, the Jerome Kern bio-pic taverses similar terrain. Of course, the nice thing about musicals like these is you can read a book or go out of the room until a musical number comes on.
