LAS VEGAS (AP) -- Leave it to Robert Downey Jr. to turn Sherlock Holmes into a wisecracking action hero who ends up handcuffed naked to a bed.

Downey has offered a sneak peek of "Sherlock Holmes," his new take on the cerebral detective from the mystery tales of Arthur Conan Doyle.

Theater owners attending their annual ShoWest convention have 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 Dr. Watson, played by Jude Law. Holmes also finds himself cuffed by both hands to a bed in one scene.

The Warner Bros. film is directed by Guy Ritchie and hits theaters on Christmas Day.
