(CNSNews.com) - Richard Dreyfuss, the actor who starred in movies ranging from "Jaws" to "Mr. Holland's Opus," told an audience in Washington, D.C., on Thursday that "there are causes worth fighting for," and one of those is the impeachment of President George W. Bush.

"There are causes worth fighting for even if you know that you will lose," Dreyfuss said during a speech at the National Press Club. "Unless you are willing to accept torture as part of a normal American political lexicon, unless you are willing to accept that leaving the Geneva Convention is fine and dandy, if you accept the expansion of wiretapping as business as usual, the only way to express this now is to embrace the difficult and perhaps embarrassing process of impeachment."
