Oscar winner Kevin Spacey, 41, has donated $100,000 to the strike funds of the Screen Actors Guild and the American Federation of Television and Radio Artists, reports the Associated Press. Since May 1, the unions have been holding a walkout against the advertising industry over fees and residuals paid to actors who appear in ads. "Since I did a film about it," said Spacey, "I have one word for the other side: negotiate." (Spacey starred in 1998's "The Negotiator.") He added that he hopes his contribution will inspire other actors to donate.
