In the days before video and (lord help us) DVD, there was 8mm. We used this format for home movies and serious hobbyists would even purchase severely edited versions of Hollywood feature films like SUPERMAN THE MOVIE and ALIEN. I had both these half hour versions on 8mm sound film during the 1970s (in fact I still have them).
But the pride of my "movie" collection was this short, CALLING ALL GIRLS, which was structured like a magazine article in which we'd see the audition process, with the call going out to Central Casting, then several sumptuous Busby Berkeley routines from the classic Warner Brothers musicals of the 1930s.
I was very proud of this film because I'd found it for about £8 ($14) at London's famous flea market, Brick Lane - this was at a time when the edited feature films cost about £30.
Perhaps this stuff seems cheesy to modern audiences, but I've loved these musicals since I was a kid, so it might be hard for me to be objective.
I haven't watched it for years as I've not owned a projector since 1980, but I remember this well and would love it to turn up on TCM so I could get it on disk. Better yet, I wish TCM UK would screen some of the original musicals ... though there's nothing quite like watching the movie in a darkened room, the image ten feet square on the screen with the whir of the projector barely masked by the blaring soundtrack.
And they say nostalgia ain't what it used to be ...
