Fabulous Fiction Bookstore used to have a video club in the back of the store, and chief among their best offerings was a block of wood with a BW Xerox poster on it which they called DOUBLE FEATURE PRODUCTIONS— and it was something they supposedly got from Pentagram Library in Worcester MA— it was a LP (4 hour) VHS video of three feature films (so I guess they should have called it TRIPLE FEATURE productions) but it also had vintage prevues, cartoons and serial chapters.
I don’t remember specifically what titles they had but I do know that often there was a Universal Sherlock Holmes with Basil Rathbone and I know for certain THE STRANGE CASE OF DR RX also from Universal was one of the features, DANGER ON THE AIR was another. Serials that were run 3 chapters to a tape were ADVENTURES OF CAPTAIN MARVEL and the DICK TRACY series from Republic. They also had KING OF THE ROCKETMEN and THE CRIMSON GHOST.
Those days are long since gone but in my studio I run a house based streaming service which features these very same films and serials on a regular basis as an homage to those glory days.
I set up the Network using either FILEBROWSER or EMBY either of which will work with various devices around the house— while on a dedicated removable hard drive called GARGANTUA I put a bunch of MP4 files which I then put into a playlist called SATURDAY AFT MATINEE— these will be 15- 18 hours long and I let them run while I work.
Right now the series I’m watching features KING OF THE ROCKETMEN as the serial and it’s showing such features as SHERLOCK HOMES AND THE SCARLET CLAW (1944) and MANPOWER (1941). These are a lot of fun and I really enjoy having them on.
