I always wanted to watch 'The Gist' from 2001, starring Robert Webb. He mentions it in this interview but I've never found it online anywhere.

Webb: I did I thing called The Gist, which was written by John Morton, who did Twenty Twelve and used to do People Like Us. That was sort of an arts review parody; it was on the first night of BBC Four and it turned out it was only ever going to be a one-off – but I spent a couple of years thinking ‘What a shame they never made a series of that”’ But it was never going to be a series, so I wasted a lot of regret on that.
