There is no doubt that multi-award winning playwright Luis Valdez is a brilliant playwright, earning his stripes with his innovative “Zoot Suit,” which premiered in 1978 at the Mark Taper Forum and subsequently made history by becoming the first Chicano musical to hit Broadway.

Sunday Bloody Sunday has been praised to a pulp, and that is understandable; it looks so ostentatiously intelligent and restrained. It has no plot, but a set of circumstances: a bisexual triangle in which Bob, a young London artist, is having simultaneous affairs with Daniel, a middle-aged homosexual doctor, and Alex, a divorcee in her thirties who works as an employment counselor.

Every chronicle play is a reduction of history. In a great chronicle play, this reduction means compression of events, intensity, selection — an artistic vision of history; Marlowe’s Edward II concentrates 24 years (1307-1330) into five credible acts. The Lion in Winter is another sort of reduction: It diminishes a struggle for the English crown into situation comedy.

The Go-Between (1971, Columbia) is the third film Joseph Losey has directed from a Harold Pinter script. Its virtues and defects are so much those of the first two (The Servant, 1963, and Accident, 1967) that Pauline Kael’s judgment on Accident fits — “a fascinating, rather preposterous movie, uneven, unsatisfying, but with virtuoso passages of calculated meanness.”

As an entertainment (“chewing gum for the eyes,” to apply John Mason Brown’s view of TV), Bullitt (Warner Bros. – Seven Arts) must be considered “a good buy”: It holds the attention for the whole of its 114 mins. Problems are mostly concealed by the film’s hip stances.

Dario Argento’s debut feature, The Bird with the Crystal Plumage (UM Film Distributors), is assured, inventive, put together with a self-renewing energy and glee. No explanation is necessary and none should be permitted.

Fogged with the Easy Rider air of self-defeat, Five Easy Pieces is much stronger on feelings than on insight. It’s not art but still affecting; the actors under Bob Rafelson’s direction lend a certain truth.

The Girl on a Motorcycle (Warner Bros. – Seven Arts) is not a title likely to attract studious filmgoers, and on the whole it is perhaps just as well. But the movie succeeds at what is seldom attempted — re-creating a poetic novel’s imagery in visual terms.

Gillo Pontecorvo’s The Battle of Algiers (Allied Artists) was the hit of the 1966 Venice Film Festival and enjoyed a highly successful run in New York the following year. The film would be welcome at any time; considering the junk we have been asked to watch so far this year, it is an especially great pleasure.

Deep End (1970, Paramount) is Jerzy Skolimowski’s seventh film, but the first to get a run in these parts. In 1968 Christian Braad Thomsen called him “probably the most explosive and original film-maker in Eastern Europe.” That is a bit much (Jancsó? Makavejev?), but his work is important and Deep End is representative of it.
