All awards, honorary and competitive, will be presented at the annual Oscar show on Monday, Mar. 28.

The new Woody Allen comedy, untitled during Production and editing, has now acquired a title, the slightly baffling "Annie Hall," and a definite New York opening date, April 20. Presumably, the Washington premiere will soon follow. While the plot remains a mystery, "Annie Hall" appears to be a romantic comedy-fantasy with a contemporary New York City setting. The leads are Allen, Diane Keaton and Tony Roberts, who composed the romantic triangle in "Play It Again, Sam." The supporting cast includes Paul Simon, Carol Kane, Janet Margolin, Shelley Duvall, Colleen Dewhurst, Christopher Walken and Jessica Harper. Allen collaborated on the screenplay with humorist Marshall Brickman his co-writer on Sleeper."

"Black Sunday," John Frankenheimer's film version of the best-selling thriller about a terrorist conspiracy to commit mass murder and panic at the Super Bowl, opens Friday, April 1, at five locations in the Washington area - K-B MacArthur, Landover Mall, Springfield Mall, Tysons Twin and the new White Flint multiple. The starring roles are played by Robert Shaw, Bruce Dern, Marthe Keller, Fritz Weaver and the Goodyear Blimp.

"Pumping Iron," George Butler's film version of the photojournalistic book about weightlifters that appeared a few years ago, arrives at the Dupont Circle on Friday, Feb. 18. The documentary surveys leading contenders for the 1975 Mr. World title, particularly Arnold Schwartzenegger, seen earlier as the easygoing muscleman in "Stay Hungry." The current attraction at the Dupont Circle, Alain Tanner's "Jonah Who Will Be 25 in the Year 2000," transfers to the Inner Circle on Feb. 18. Jeanne Moreau's "Lumiere" will be in the wings at the Inner Circle and Barbara Kopple's "Harlan County, USA" at the Dupont Circle.

"The Sentinel," a horror melodrama with Cristina Raines as a fashion model courted by Chris Sarandon and menaced by Burgess Meredith, Sylvia Miles and other sinister types, is scheduled to open Friday at several area theaters. "Rocky" adds eight more locations this week while holding over at the Avalon and Roth's Tysons Corner. Secondary engagements begin next Wednesday, Feb. 16, for "Network," "The Pink Panther Strikes Again" and "Carrie."

William Katt, who made a sensational movie debut in "Carrie" as Tommy Ross, the high-school dreamboat, will play one of the leads in "First Love," a movie version of a Harold Brodkey story about college students in love. A female lead has yet to be named, but production is scheduled to begin this month, with Joan Darling making her feature film directing debut. Lonette McKee, the scintillating Sister in "Sparkle," will be one of the two women complicating Richard Pryor's life in "Which Way Is Up?," an Americanization of Lina Wertmuller's "The Seduction of Mimi" now being directed by Michael Schultz of "Cooley High" and "Car Wash."
