Billy Bob Thornton insists 'Bad Santa 2' will not be as good as the original film.

The 59-year-old actor played an alcoholic thief who worked as a department store Santa Claus to steal from shops in the 2003 movie, and while he is still waiting to see a script for the follow up film, he has already conceded it will never be able to better the first motion picture.

He said: ''We're just waiting for a script, you know. I mean we're never going to beat the first one but you got to get as close as you can.

''I mean, you know you just can't go out there and do it halfway. So we're waiting for something that's close enough. And you know it will do real well, I would imagine.

''And then you know people will say, 'Well, it wasn't as good as the first one.' And we'll say, 'Yeah, we knew it wouldn't be.' But I think it should be fun. I think people who like this one will enjoy it. And hopefully we'll get it off, yeah.''

Thornton joked he was drinking from 7am on the set of the original movie and insists acting in a comedy film can be a lot harder than starring in a drama because the audience are expecting a laugh.

Speaking to The Hollywood Reporter, he joked: ''I prepared for this one by drinking from 7:00 o'clock in the morning.''

He then added: ''But yeah, I mean comedy is different. There's no doubt about it. And when they say comedy is harder than drama, in some ways it is because with comedy you're expecting a result, you know, from the audience.''
