John Burstein really puts his heart—and his lungs, stomach and liver—into his work. In a body stocking painted with designs of his internal organs, the 25-year-old actor regularly tours the New York City school system as "Mr. Slim Goodbody." Incorporating his dance training with imaginative and catchy tunes of his own composition about health, he has already invited 200,000 youngsters to "take a look inside and see...what goes on inside of me." In "Lubba-Dubba," for instance, he explains the heartbeat. Son of a prominent labor lawyer (father) and State Supreme Court judge (mother), the Hofstra College graduate conceived "Slim" in 1973 as an entertainer with New York's Floating Hospital, a boat equipped to give medical examinations to disadvantaged kids. A 5'10", 155-pound bachelor, Burstein soon hopes to tell even more kids "The Inside Story" through an upcoming record album and film and a projected cross-country tour.

Elizabeth Cheshire's TV debut as the winsome stepdaughter of a knockabout musician on the sit-com Sunshine earned accolades from such critics as Cecil Smith of the L.A. Times, who credited the 8-year-old actress with "remarkable assurance and charm." Although NBC will not renew Sunshine next season, Liz is hardly likely to be unemployed. She now finds her craft "a breeze." Good thing. The daughter of an L.A. TV-station stage manager, Liz has had to bag earlier dreams of working in an ice cream parlor. "I'd eat too much and get fired."

Chuck Braverman, 31, believes that the "big flaw" in film schools (he graduated from USC's in '67) is their failure to "teach you how to get a job, how to hustle." Braverman's door-opener to the biz was his exploitation of a sophisticated technique called "kinestasis"—a subliminally fast mix of still photos, graphics, animation and motion picture footage with which he has concocted such oddities as a three-minute romp through 200 years of history. Called "The American Time Capsule," Braverman first scored with it on the Smothers Brothers' CBS series in 1968. Since then his major documentaries—on such subjects as welfare recipients, black history and childbirth—have earned him an Emmy and other high professional honors. But what butters the bread over at Braverman Productions on Sunset Boulevard (and also allows the boss his passion for skiing and motorcycling) are commercials and the titles he produces for such TV shows as Cher and Rhoda. Recently married, Braverman contemplates the next logical step, a feature film. The subject? "The kind that people will like, so I can make money to make more films that people will like."
