Billy Bob Thornton, on the other hand, got boozed for his drunk scenes in Bad Santa, which, you know, isn’t exactly tough.

De Niro would probably have delivered a present to every kid in the world in one night, inebriating himself only on the wine he found in their houses. And then he would have done the scenes, in sequence, in one take. Whilst juggling.

De Niro rating:   Bobbys out of ten
