Alan Rickman in the play 'Old Times' also featuring Lindsay Duncan and Gina McKee. If you're in the reading mood, here's more info on the play: en.wikipedia.or...
LOL. no worries :) More info on this would be great. I didn't find much info on it. Your idea of it being a tribute makes sense, it looks fairly recent.
I'm not sure how long it is. The clip right after this was from a diffplay. So I'm not sure if they actually performed the whole story or just this segment... The gist of the plot, from what I can understand is about a married couple -Rickman & Duncan, who are talking about the wife's old friend -McKee, who is visiting them. Turns out the friend fancies the wife and starts to win her attentions. Which doesn't go well for Rickman, so they both start to 'compete' for her.
