If it were a new series, there would have been a lot of publicity behind it.
No new series has been made.
The feature film and stage shows were the last things from The League of Gentlemen.
You can sometimes catch the original radio show on BBC7, now retitled, "On the Town with The League of Gentlemen".
From what I have seen it is the third series - the one where all the stories tie in together in the last few minutes (the red plastic bag, the joke shop owner and the white van crashing).
fantastic 3 series of comedy but they pushed it a bit too far. i was a massive fan of series 1 and 2 but 3 didnt quite live up to expectation and lets not even mention the film !
