I realise that this thread is very old, but I was pleased to see Mr Irons mentioned. I fell in love with both Jeremy and Anthony Andrews in Granada's Brideshead Revisited mini-series.
Incidentally, Jeremy has two rather handsome sons - the youngest, Max, is truly beautiful and was featured in a Burberry ad campaign alongside Kate Moss. See the attached images - in the first, he is the tall! boy on the left, and the second is of Max and his father.
