There's a newish channel on freeview called Sky Movies Classic. It's worth a look if you find yourself at a loose end.
When I got in from work on Monday it was in the middle of a small Marlon Brando tribute comprising The Wild One at five past five followed by On The Waterfront at quarter to seven.
The Wild One was made in 1953. It was banned by the British Board of Film Classification upon its release and remained so (except for screenings in film societies where local councils overturned the BBFC’s decision) until 1967 when it was released with an X certificate.
Now they show it in a time slot where only school children can see it as the 9-5 wage slaves can't get home in time.
