LOS ANGELES - The unrattled Sherlock Holmes gets his greatest test this spring when he comes face to face with - gasp! - full frontal nudity. No, Watson doesn't drop his pants. Instead, "Sherlock II," which airs on PBS in May, features a dominatrix who may be as smart as our detective.

Reporters at the TV Critics Press Tour pounded actress Laura Pulver,with questions about the scene in which her character tries to get Holmes off his game by taking it all off. The scene got a lot of attention when it aired earlier this year in Great Britain, even though viewers didn't actually see any naughty parts.

"It was no mean feat for me to shoot it, being naked for eight hours in just a pair of Louboutin shoes," Pulver said.

Critics kept bringing up the subject during the press conference, which was just fine with Holmes portrayer Benedict Cumberbatch, who joined the session via satellite from London where he is shooting the part of a villian in the upcoming "Star Trek" movie.

"If it creates more interest in the program, thank you very much for that," he said.
