Yo! Stella!

SYLVESTER STALLONE might want to brush up on his “Yo, Juliet!” speech. The buzz is that the under-employed action hero is hot to hit the stage and do some serious theater, particularly in England. Theater performances have boosted or revivied the careers of such stars as NICOLE KIDMAN (“The Blue Room”) and KATHLEEN TURNER, who has been getting raves in London for baring it all in “The Graduate.” STALLONE‘s career could certainly use a boost. “I have not made a dime in two years, ” the one-time hot star complained to Stiffed author SUSAN FALUDI last year. “I see everyone else working and I’m not doing (bleep). I’m in total limbo.”

A spokesman for STALLONE denies that he wants to do theater, but London’s Express quoted a “theatrical agent” as saying, “It’s on the QT that we’ve been asked to find out if there are any suitable projects floating around for him.”

While some theater sources scoffed at the idea of the star of “Rambo” and “Rocky” doing theater, others were less skeptical. “He’d make a great Stanley Kowalski,” says a source, refering to the leas in “A Streetcar Made Desire.”
