Funny Girl--If you like Barbra Streisand, there is no getting around the fact that this movie works. The score, the screenplay, and even Omar Sharif are fine. The photography, on the other hand, is unfortunate, as is the editing. At the CHERI 2, Dalton St. in Prudential Center (536-2870).

Great Catherine--Claims to be derived from Bernard Shaw's obscure one-actor, with Jeanne Moreau, Peter O'Toole, Zero Mostel. At the CHERI I Dalton St. in Prudential Center (536-2870).

Head--The Monkees "star" in a tediously authentic paranoid freak-out stupidly filmed in living Technicolor. Your first inclination might be to go stoned, but don't take the chance. At the WEST END, North Staton (523-4050).

Hot Millions--Peter Ustinov and Maggie Smith are just fine in this gentle suspense-comedy written by Ustinov and Ira Wallach. At the ASTOR, Tremont St. near Boylston (512-5030).

King Kong--In which we learn that beauty killed the beast, not all those wooden airplanes buzzing the Empire State Building. Definitely one of your great gorilla pictures. At HILLES LIBRARY, tonight.

The Lion in Winter--Pretension unleashed, most notably that of Anthony Harvey, the director, who seems bent on doing everything as conspicuously as he can. Neither Peter O'Toole nor Katharine Hepburn gives much of a performance in this cumbersomely filmed version of James Goldman's play, which was unconvincing to start with. At the PARIS CINEMA, 841 Boylston (267-8181).

Mississippi--A Bing Crosby picture in which W. C. Fields gets to do some schtick. Shown with a Road Runner cartoon at 2 DIVINITY AVE., tonight.

Negatives--Glenda Jackson (Charlotte Corday in the Peter Brook Marat-Sade) is in it. At the CHARLES, 195 Cambridge (227-2832).

Never Give a Sucker an Even Break--One of W. C. Fields' best, with Margaret Dumont and a wild movie-within-the-movie. At SYMPHONY II, 262 Huntington (262-8820).

The Oldest Profession--Raquel Welch, Jeanne Moreau and Elsa Martinelli show what that is all about. At the CENTER, 686 Washington St. (426-0889).

Rachel, Rachel--An honest little movie, the first to be directed by Paul Newman, which gives Jeanne Moreau room to deliver a fine performance and carry the day. At the HARVARD SQUARE (864-4580) and SYMPHONY I, 262 Huntington (262-8820).

Romeo and Juliet--Although Franco Zeffirelli's teen-age treatment of Shake-speare's situation tragedy may be somewhat free-wheeling for all tastes, sentimentalists will eat up every second. Olivia Hussey's reading of Juliet proves a truly right interpretation of the part. At the ABBEY, 600 Commonwealth Ave. (262-1303).

Rosemary's Baby--Dangerously misdirected by Roman Polanski, irritatingly acted by Mia Farrow and John Cassavetes, shoddily filmed in grainly bleached-out color, vehemently hated by your friendly Crimson reviewer, but far-and-away the most popular film of the year. See for yourself. At the ESQUIRE, Mass. Ave. on the Boston side of Harvard Square (491-7730).

Shalako--Sean Connery and a heavily made-up Brigitte Bardot in a western which instinct tells us isn't much good. To be reviewed next week. At the PARAMOUNT, Washington St. across from Raymond's (482-4820).

Star--Despite wonderful music, ranging from Kurt Weill to Cole Porter, an aimless, fruitless movie. The theatrical history, however, is fun, and Julie Andrews and Daniel Massey are likewise as Gertrude Lawrence and Noel Coward. At the GARY , 131 Stuart (542-7040).
