"3 Ninjas" is the unlikely winner of Hollywood's unofficial award as most profitable flick of 1992. The picture grossed $28.8 million for Disney, but cost the studio only about $2.5 million. Other winners in the cost-to-gross ratio were "Sister Act," "Wayne's World" and "The Hand That Rocks the Cradle."

- The wife of Nirvana lead singer Kurt Cobain has sued her doctor and famed Cedars-Sinai Medical Center, claiming they leaked information about alleged heroin treatment she received while pregnant. Courtney Love, herself lead singer for Hole, asks unspecified damages from the hospital and Dr. Michael Horwitz. Her lawyer says she could collect up to $1 million.- Jack Nicholson told Entertainment Weekly why he almost never grants interviews.

"I don't want people to know what I'm actually like," he explains. "It's not good for an actor. . . . Anybody can fool the audience in one picture. The hardest thing is after they know you, how do you reconvince them that you're not you but Jimmy Hoffa? Or Nathan Jessep in `A Few Good Men'?"

- Screen kids say their biggest challenge is keeping up with both schoolwork and acting chores. "I'm really lucky that everyone abides by the (child labor) laws," says Tatyana Ali, 13, of "The Fresh Prince of Bel-Air." "But it's tough going to school and then going back to the set."

Echoes Alisan Porter, 11, star of "Curly Sue" and "Parenthood," among other flicks, "The big challenge is the schoolwork because you're having a tutor on the set and don't get to go to regular school, as well as having to do a scene with so many different shots with hair and makeup. It's hard to get schoolwork in as well as do the job."
