Since we seem to have come to an end with the movies based on UK comics characters how about the TV series? I suspect that a lot of this will depend on peoples ages as most of the ones I can think of are cartoons from children's television.
Modesty Blaise (1982)
Live action based on Modesty Blaise from the London Evening Standard
Originally broadcast on US TV http://www.imdb.com/title/tt0217658/
I think that comics related TV ads are another list for the future, as fun as the three Dan Dare Mobil ads are, to go with the ad for 2000AD in our videos section, and possible ads for Cracker and TV21.
How could I have forgotten about CGI Dan? Maybe because I never got the DVD of the series. The third Comics Britannia reminded me about the Viz characters, so here are the latest additions.
Roger Mellie: The Man On The Telly (1991)
Cartoon based on Roger Mellie The Man On The Telly from Viz
Originally broadcast on Channel 4 http://www.imdb.com/title/tt0390760/
