I Am a Camera (at the Brattle Theatre through Saturday). Julie Harris puts on airs in one of her incandescent performances.

Man In the White Suit (at Loew's Strand Theatre in Back Bay through tonight). The semi-science-fiction classic from the Alec Guinness canon of comedy.

Edge of the City (at Loew's Lancaster Theatre near North Station through Saturday). The moving tale of an intelligent Negro who befriends a confused white youth--both in the grips of a racially bigoted foreman. One of the decade's best films, with flawless performances by Sidney Poitier, John Cassavetes and Jack Warden.

Something of Value (at the Shopper's World Cinema in Framingham). Hard-hitting transferral to the screen of Robert Ruark's harder-hitting best-seller about the white British versus the black Mau-Mau in Africa. Laudably, the complex issues are not oversimplified; and both sides are properly shown to be at fault. Superlative performances by Sidney Poitier, Wendy Hiller and Juano Hernandez. Even Rock Hudson is good; and Dana Wynter's appearances are fortunately brief.

High Noon and The Moon Is Blue (at the V.F.W. Parkway Drive-In in West Roxbury). A pair of fine cinema classics with Gary Cooper and Grace Kelly in the first, William Holden and David Niven in the second.

Desires (at the Brattle Theatre this Sunday and Monday). A sensitive German film about a ballerina who is addicted to morphine.
