As the world turns
"Soapdish" is a frequently hilarious spoof of the wild and wacky world of television soap operas. In the film, Sally Field plays Celeste Talbert, a soap star whose life parallels that of the character she is playing. The film is off target for a time, but then Kevin Kline appears and everything is back on track. Mr. Kline plays Jeffrey Anderson, a former soap opera actor who is now doing "Death of a Salesman" in dinner theaters. That ought to give you an idea where this movie is going. Whoopi Goldberg plays one of the show's writers. Language. Rating: PG-13. *** White Marsh Dinner Theatre is starring the adroit comedian and singer Nancy Tarr Hart as the lovable matchmaker in the popular Jerry Herman musical "Hello, Dolly."

"Mermaids" presents Cher as the free-spirited mother of two girls, one of whom lives in a fantasy world. Winona Ryder plays the older daughter caught up in her fantasies, and Bob Hoskins is the man who loves the girl's mother but can't persuade her to settle down. Richard Benjamin directed the film, and he overdoes it at times, but Cher, Ms. Ryder and Mr. Hoskins are so good they more than compensate for the directorial excesses. Language, sex. Rating: PG-13. ***
