Guy Ritchie's plan to put a gay spin on the relationship of Sherlock Holmes and Dr. Watson in his new movie about the detective and his sidekick could backfire.

Robert Downey Jr., who plays Holmes, has revealed the crimebuster will sleep with and have sweaty grappling scenes with Watson, played by Jude Law, in "Sherlock Holmes," due out Christmas Day.

"We're two men who happen to be roommates, wrestle a lot and share a bed. It's bad-ass," Downey told Britain's News of the World. Added much-in-the-news Law: "Guy wanted to make this about the relationship between Watson and Holmes. They're both mean and complicated."

But Michael Medved, a former Post movie critic, says Downey and Law must be joking. "There's not a seething, bubbling hunger to see straight stars impersonating homosexuals," Medved told us. "I think they're just trying to generate controversy . . . They know that making Holmes and Watson homosexual will take away two-thirds of their box office. Who is going to want to see Downey Jr. and Law make out? I don't think it would be appealing to women. Straight men don't want to see it."

Roger Johnson, editor of the Sherlock Holmes Journal, observed that in Arthur Conan Doyle's original stories, "Watson is something of a ladies' man, but a faithful husband to his wife. And Holmes is essentially asexual, with no erotic interest in women or men."
