Nude? Handcuffs? Sherlock, is that you?

Sherlock Holmes naked? Handcuffed to a bed?

Those are the reports after a sneak peek Tuesday of

Robert Downey Jr. Arthur Conan Doyle

’s famous sleuth.

In Downey’s “Sherlock Holmes,” due in theaters Christmas Day, the detective is a ladies man with a lady love (

Rachel McAdams

.) Conan Doyle’s Holmes lived a virtual monk’s life, save for one platonic dalliance with a certain female foil whose brain he admired.

Theater owners attending the annual ShoWest convention got to see Downey’s Holmes in a bruising boxing match, diving from a tall building into London’s Thames River and trading barbs with roommate Dr. Watson (

Jude Law

), who complains about the detective’s slovenliness and nocturnal violin playing.

“Holmes, does your depravity know no bounds?” Watson asks the detective.

Despite the saucy swagger and attitude of Downey’s “Sherlock Holmes,” directed by

Guy Ritchie

, the actor said the movie is true to the spirit of Conan Doyle’s stories, which have plenty of action.

Past screen adaptations of Holmes stories “just never had the money to do it right,” Downey said.

Downey joked that after his superhero flick “Iron Man” had a blockbuster opening weekend last year, his agents told him he had a window of the “next hour and a half” where he could do anything he wanted in Hollywood.

His agents told him “don’t do anything crazy,” Downey said.

Like putting Sherlock Holmes in handcuffs?
