Maggie Cheung, one of Hong Kong's best-known actresses, says she's more selective about movie projects because she wants to avoid films that only capitalize on her star power, a magazine reports.

"The problem is I want good quality. I've tried not to play the same characters because I want to try new motions and new challenges," Cheung was quoted as saying in the current issue of Hong Kong City Magazine.

She said "Clean," for which she won best actress at the Cannes Film Festival, is a recent example of a good movie she took on. Cheung plays a rock star junkie who tackles parenthood.

Other than "Clean," released in 2004, Cheung also appeared in art-house director Wong Kar-wai's "2046," also released in the same year.

Other films in recent years include Wong's "In the Mood for Love" (2000) and famed Chinese director Zhang Yimou's "Hero" (2002).
