I can't think of many channels where I'll always check what's one but Talking Pictures is the main one. Theres always at least one decent thing on it a day.
Earlier Hell Drivers was on, one of the favourite films of all time. Now and again they show wonderful shorts like Teaching GIs how to act in the UK with Burgess Meredith (Although Wales' capital at the time wasn't Aberystwyth as claimed but Caernarfon) and a wonderful short about the trains sending the post in the 30s. It's very heavy on some of the very greatest British Cinema ever.
Evwn better its run from a garden shed by a film enthusiast who did a deal with the BFI and even more so buying rights for films off the BBC for old films they thought no-one would watch. They were dead wrong. It's one of the most watching stations in the country now. Huge figures considering. I like to think it's D Mal. Also they have the best knowledge of their market ever. Most channels show teleshopping from 3 to 7, they knew their elderly watchers are all up before sparrow fart so fucked off teleshopping and made a killing. Its just a wonderful channel.
Charade is on at 3:45am for example. Proper cinema.
