Actor Johnny Depp, who has been slammed by experts for misinterpreting key words in Paul McCartney’s video ‘My Valentine’, says he was just following the instructions. The critics were unhappy with Depp’s sign-language skills in the video that he recorded with Natalie Portman. “I had to learn sign language and I was only copying what the guy showed me, so track him down,” thesun.co.uk quoted the 48-year-old as saying. “Apparently, instead of ‘love’ I might have said ‘murder,” he added. Depp also says he feels that sign language is interpretive. “But it was a gas – sign language is apparently very interpretive. It’s all kind of different,” he said.
