He has always been on hand to issue condemnations of Israel for daring to defend itself against terrorism (such as being a signatory on this anti-Israel blood libel letter) and appear at events run by the anti-semitic Palestine Solidarity Campaign. He tried to take his activism to a different level in 2010 by starring in a film ("The Promised Land") that attempted to rewrite the history of Israel with a whole bunch of anti-Zionist lies (thankfully - as pointed out by commenter Ian - the film was abandoned before it was released).
UPDATE: As reported here it turns out that the script for the new Bridget Jones movie was actually co-written by none other than Israel boycotting witch Emma Thompson. And it seems the movie is even pushing her anti-Israel propaganda as reported by Debbie Schlussel:
The first thing you need to know about this movie is that it co-stars and features a script co-written by Israel-boycotting Jew-hater Emma Thompson. I don’t support movies that finance anti-Semites, but I reviewed this with an open mind on its own merit (even though I recommend you give Fraulein Thompson the back of the hand). I couldn’t help but notice, though, that there is a dumb, snide line (among many in this film) about needing to “get footage of the attack on Ramallah.” Um, what attack on Ramallah. If anything, the Palestinian Muslim terrorists in Ramallah are attacking synagogues, bars, bus stations, etc. throughout Israel. Got that, Emma?
