Some kind soul has uploaded BBC’s Arena Cinema program on Star Wars - from 1979 - up on youtube:-

'This episode of ‘Arena Cinema’ was broadcast on BBC2 on 29th January 1979 to co-incide with the British release of ‘Star Wars’. What we have here is an interviews and analysis. Behind-the-scenes clips are included, some of which I haven’t seem elsewhere.

The format of this series was that each episode had a lengthy feature item with unrelated film news and reviews at the end.

Short clips of this programme have been seen elsewhere over the years. To my knowledge it has not been repeated since.

I’ve had to make edits to comply with YouTube’s filter. The missing footage is clips from the film.’
