Sir Michael Gambon and Melanie Laurent are among the stars who have stripped off to show their support for a sustainable fishing campaign. The Harry Potter star sheds his shirt and holds a blowfish to promote the Fishlove project, which aims to raise awareness of over-fishing in Europe's seas. Laurent, who is pregnant with her first child, poses topless with only a crab to preserve her modesty, while famous faces including actors Arthur Darvill and Simon Callow, theatre director Steven Berkoff and actress Zoe Tapper also take part in the campaign. Inglourious Basterds star Laurent says, "The fishing crisis is quite complex and difficult for people to understand, but this was so simple. It said everything that anyone needed to know about the fishing crisis: if we don't start protecting fish, they will die out."
