From July Film4 will launch on freeview and go FTA on Sky. I'd imagine it'll also go into the base pack on Ntl/Telewest.

to this one. I've always found that Film4 shows much better films than the Sky movie channels.
The only problem is the ad-breaks that'll be introduced but I suppose you can't have everything.
