I do love Joaquin Phoenix. Walk the Line is one of my favourite films of recent years, one of those you have to watch when it's on telly even though you've got it on DVD (as I did only the other night). He's just done this video for PETA, "Cold-Blooded Horrors: Inside the Exotic-Skins Trade" (wish I could embed, but technology fails me). Please watch, it's powerful stuff.
I hope someone shows Samantha Cameron a copy.
