Yes its true. Actor Cary Elwes was in a grocery store buying his weekly shopping when he spotted none other than Spielberg himself and got offered a part in Tin-Tin.
“It’s a funny story if you’ve got a second. Steven Spielberg came down to the set of A Christmas Carol because he’s friends with Robert Zemeckis and was there while I was filming a scene - no pressure! He came over afterwards and said, 'I’m shooting Tintin. It’s got Jamie Bell and Andy Serkis and it’s going to be a lot of fun.' And I said, '[Stutters] Mr... Mr... Spielberg, I’m a really big fan of Tintin. I have to be in it.' He did that Hollywood thing: 'Yeah, yeah, we’ll see.'"
"Then two weeks later my wife and I are in a grocery store, and my wife says, 'Honey, that’s Steven Spielberg.' I say there’s no way Spielberg is grocery shopping on his own; he has people to do that for him. But there he was, shopping for cereal by himself. So I went up to him and said, 'Steven... er, Tintin?' [Laughs] He said, 'You know what, I think I have one part left. Do you speak French?' and I said [adopts best Clouseau impression] 'But of course!'”
So there it is. If you fancy appearing in War Horse, try the Tesco's nearest Dartmoor. Cereal aisle. Thats two stories today about Spielberg and shopping. Anyone got a third?
