Celebrity Rosie, Martin Aid Strikers By Stephen M. Silverman Published on July 17, 1998 12:00 AM Share Tweet Pin Email Kevin Spacey, George Clooney, Jay Leno, Bruce Willis . . . and now Rosie O’Donnell, 38, and Martin Lawrence, 35. The two have joined the growing list of actors who have reached for their checkbooks to aid the Screen Actors Guild Foundation’s strike relief fund as the union’s strike against advertisers grinds on. As of Friday, the walkout is 159 days old. Variety reports that the TV talk show queen’s contribution was $50,000, while the star of “Big Momma’s House” pitched in $20,000. “As fast as the money comes in,” said the foundation’s executive director, Marcia Smith, “it goes out again.” So far, Smith said, celebrity donations have amounted to $730,000, and the fund has taken on nearly 400 cases since early August. Most of the requests from the out-of-work actors have been for mortgage and car payments, utilities and health insurance, said Smith. Strikers reportedly plan to air their grievances at the annual shareholders meeting of Procter & Gamble, a key TV advertiser, in Cincinnati on Tuesday.
