Melbourne:Serena Williams is working on a movie script on the life of Althea Gibson, the American tennis player who won five Grand Slam singles titles in the late 1950s and was credited with being a forerunner for other black athletes. "I think Althea Gibson has a great story ... we're working on a script right now," Williams said Friday at the Australian Open after her three-set win over Nadia Petrova. Williams said Gibson, the first black person to be voted by The Associated Press as its female athlete of the year in 1957, had been "a little bit overlooked". "I just feel sometimes that Althea Gibson, who did so much for people like me to play this sport, and she was the first, before even Arthur Ashe, and I just think it will be a great story to tell." Williams said other players had been honored. "You've got the US Open, you've got the Arthur Ashe court - Arthur Ashe is a great guy, and it was my lifelong dream when I met him," Williams said. "Then you have the Louis Armstrong Center and the center being named after Billie Jean King, who, again, I always admired Billy, and she's someone that I love." Gibson, who won two singles titles each at Wimbledon and the US Open, and the French Open once, died in 2003 at the age of 76. When asked what her status could be on the movie, Williams replied: "I definitely won't be directing it. Hopefully I can produce it or something."
