London, Dec 7 - Hollywood actor Robert Pattinson, who shot to fame after the success of "Twilight", says he is scared of not fulfilling fans' expectations.

"Before 'Twilight', I did any movie that I got offered. But now fans expectations have doubled and I just can't mess around," femalefirst.co.uk quoted Pattinson as saying.
