Actress Lynn Redgrave is putting some professional distance between herself and sister Vanessa.

Lynn fears that her sister's politicial outspokenness may harm her own career, the Ladies' Home Journal reported in its May issue. Lynn said she'll probably change her last name to Redgrave-Clark to avoid any confusion.Vanessa publicly opposed Western intervention against Iraq's invasion of Kuwait, while Lynn supported President Bush's actions. Vanessa was recently dropped from a U.S. tour of the British comedy "Lettice and Lovage."

"I'm very proud I come from my family," Lynn said. "But Vanessa crossed a line. This is the strongest I've ever had to be in opposition to her."

Lynn, 48, lives in Los Angeles, with her husband, John Clark. Vanessa, 54, lives in London.
