Christopher Lee is only interested in playing smaller film roles that "mean something".

The 89-year-old star is set to reprise his role of Saruman in 'The Hobbit: An Unexpected Journey' and 'The Hobbit: There And Back Again' after playing the part in the 'Lord Of The Rings' trilogy, but he is picking and choosing his roles carefully nowadays due to his age.

In a video posted by TheOneRing.net, Christopher said: "I don't play long parts. They must be short parts, but they've got to be parts that mean something, that matter, where people will notice when I'm on the screen and people will remember the character after they've seen the film."

Christopher revealed 'Lord of the Rings' characters Aragorn and the Rohirrim will not appear in 'The Hobbit: An Unexpected Journey' and 'The Hobbit: There And Back Again' - which are set to be released in 2012 and 2013 respectively - and his character will turn out to be a "good man" in the prequel movies.

The 'Hugo' actor - who has already filmed his two parts for both films - explained Saruman returns as "a good and noble man and the head of the Council Of Wizards, as he had always been".
