Sir Anthony Hopkins thinks the process of ''flattering'' people to win an Oscar is ''disgusting''.

The 74-year-old actor - who previously won an Academy Award for psychological thriller 'Silence of the Lambs' in 1991 - admits he is not keen on the idea of having to work up publicity to win a nomination for his new film 'Hitchcock' because it is ''against'' his ''nature''.

He said: ''You know, I've been around - I've got the Oscar myself for 'Silence of the Lambs' - and having to be nice to people and to be charming and flirting with them ... oh, come on! People go out of their way to flatter the nominating body and I think it's kind of disgusting. That's always been against my nature.

''You know, kissing the backside of the authorities that can make or break it; I can't stand all that. I find it nauseating to watch and I think it's disgusting to behold.''

Anthony plays the role of the iconic director Alfred Hitchcock opposite Dame Helen Mirren and Scarlett Johansson in the movie, and he admits getting into make-up was one of the trickiest aspects of filming.

He told the Huffington Post: ''What was the most difficult part of preparation? I think getting the make-up right was the first one.

''It wasn't difficult in itself, but we did about four or five camera tests to modify to make sure there wasn't too much makeup. Getting the voice right, too. I watched a lot of 'Alfred Hitchcock Presents' on television.''
