APRIL and May are among the busiest months in the performing-arts calendar. Tonight, the Academy Awards will be televised from Los Angeles; and after a flurry of theater openings in coming weeks, the Tony Awards will take place in June.
In the international film community, an ongoing dispute is percolating over the Academy of Motion Picture Arts and Sciences' rule about which films qualify for its best foreign-language film award. This year, academy voters eliminated the critically acclaimed ''Red'' from consideration, saying that Switzerland, which submitted it, could not claim the picture because the director, Krzysztof Kieslowski, is Polish, and the language spoken in it is French. (Kieslowski later picked up Oscar nominations as director and co-writer.)
Increasingly, critics of the academy say the qualifying rules need to change to accommodate international films whose origins are not clear-cut.
Last year, the rules were bent to include ''The Wedding Banquet,'' submitted by Taiwan but shot in New York with a partly American crew and a large amount of English dialogue. Two other nominees from last year, ''Farewell My Concubine'' (Hong Kong) and ''The Scent of Green Papaya'' (Vietnam), were made outside the countries that submitted them.
Major Bolshoi shakeups
Ballet fans are watching to see what emerges from the disarray that has plagued Moscow's Bolshoi Theatre. On Tuesday, 34-year veteran prima ballerina, Natalia Bessmertnova, quit after the company named the person to replace artistic director Yuri Grigorevich.
During his 30 years in that post, Grigorevich had ruled the company with a firm hand, and, according to ballet critics, did not bother to choreograph new works or improve the repertoire. What he did, however, was ingratiate himself with officials and a core of loyal dancers, to whom he gave the primary roles. Grigorevich resigned March 9 after feuding with the Bolshoi's general director, Vladimir Kokonin, over Kokonin's attempts to restructure contracts.
