It’s the first show that Spacey will act in for his new Old Vic company, though he’s set to take the director’s chair himself for Maria Goos’ play Cloaca (previews begin Sept. 16 prior to an official opening Sept. 28). The Oscar-winning actor’s co-star for Philadelphia is not yet known, though Variety pegs Helen Hunt, Cameron Diaz, Nicole Kidman and Gwyneth Paltrow as all rumored to be in the frame. At a press conference earlier this year, Spacey kept his options wide open, saying that it might be a big star or an unknown.

Zaks is a seven-time Tony Award winner, bagging his last for 1996’s A Funny Thing Happened on the Way to the Forum with Nathan Lane. He directed the recent Broadway production of Little Shop of Horrors and is currently working on the New York revival of La Cage aux Folles, to star Gary Beach and Daniel Davis. He’s previously had shows in London including Smokey Joe’s Cafe and Six Degrees of Separation.
