Most of these are available on DVD, but have not been shown on TV (well Freeview) for a least 10 years (and probably more).
Harold And Maude
All are "classics" that I would like to see, but not sure if they're worth paying for,
Hmm, I might look on eBay.
Yeah, they haven't been on Freeview. However, 'Network' was on TCM about a year ago. Interesting film, I wouldn't say it was a classic but, it does seem quite relevant in this day and age(i.e. Jerry Springer, Jeremy Kyle, the power of TV, etc.).
Harold and Maude has been shown on Sky Movies. Interesting film from the 1970s. Strange subject matter.
