Even before today, there was something weirdly compelling about the poster for Righteous Kill. The awful hair. The way Al Pacino’s name hovers to the right of, but ever so slightly higher up than, Robert De Niro’s (imagine how many hours of lawyers’ time that gobbled up). The fact that it’s so much naffer than this early version, and even this one too, in which they’ve clearly just been caught snogging. And that parodically bravado tagline: “There’s nothing wrong with a little shooting as long as the right people get shot”.

Then today, someone alerted me to a photo on Popbitch of the poster at Stockwell tube station, where, yesterday, the jury in the Jean Charles de Menezes case inspected the site where he was shot dead by police who thought he was a suicide bomber. Suddenly that tagline starts looking a little less funny.

Unfortunate juxtapositions are an inevitable hazard of billboard advertising. A colleague reminds me that a poster for The Descent was on the side of the bus that blew up on 7/7. Posters for the Arnie film Collateral Damage were hastily removed on 12th September 2001.

Can you think of any more? And what is it that’s interesting here, exactly? Do we just like a morbid laugh? Or does this sort of thing jolt you into feeling queasy about entertainment that treats death glibly? Anyway, I’m feeling slightly less keen to see Righteous Kill just now.
