Rhythm and blues
''Heartbeats'' is not totally professional, and the story is much too familiar, but the film disarms with charm and niceness. Robert Townsend, who co-authored the script and directed, plays one of five young men who form a singing group in 1965. It's all here, the disharmony, the desertions, the drugs and the deceit, but Townsend and Keenen Ivory Wayans (''In Living Color''), who co-wrote the script, make it all very appealing, if not necessarily new. Language, Violence. Rating: R ** ''The Tall Guy'' is reminiscent of those English comedies starring Alec Guinness and Peter Sellers. This one may be a bit wackier than those, but it does take us back to an era when the English were leaders in the comedy movie market. Jeff Goldblum is the American actor living in London who lands the lead in a musical version of ''The Elephant man.'' Show buffs will find it all particularly amusing. Sex, nudity, language. Rating: R. ***
Horror with camp
Harbour Theatre, under the excellent direction of Jeffrey Heller, is presenting an outstanding version of the musical, "Little Shop of Horrors." With book and lyrics by the late Howard Ashman and music by Alan Menken, the play is based on the camp horror film by Roger Corman. A poor Skid Row florist discovers a miracle plant that makes him rich and famous -- with dire results. Rick Hammontree, Rodney Bonds and a very talented cast turn in hilarious performances. 8:15 p.m. 1700 York Road. Tickets: $8/$7. Call 532-2022.
