Blondeshavemorefun Nev Gallagher (George Costigan) played Bob in Rita, Sue and Bob Too back in the 1980's. Don't know if you've seen that. Originally a play by Andrea Dunbar with a VERY different ending to the film which Andrea wasn't happy about. In the original play he gets some proper comeuppance.
He's been in loads of TV, including Sally Wainwright's Unforgiven and Scott and Bailey. He's one of those jobbing actors who you recognise on TV but as he rarely plays the lead you don't usually clock his name.
Siobhan Finneran was also in in Rita, Sue and Bob Too, she was Rita. Excellent actor.
