Connect Four #2

The inaugural edition of this trial feature was too easy, so hopefully this one's a touch trickier. In fact, non-Brits may find it impossible (sorry about that). But, knowing my luck, my fellow countrymen are all on my wavelength, so I'm still half-expecting a correct answer straight off the bat...

The connected four this week are (left to right, above): Andrea Riseborough, Rory Kinnear, Bill Pullman and Colm Meaney. One thing links them all together, but what is it? Leave your guesses in the comments below, and I'll try and think up some clues if this stumps everyone...
