A MODEL ‘MOONLIGHTING’ AS A PRIVATE DETECTIVE

NBC struck first with “Remington Steele,� pairing a veteran private investigator with a novice of the opposite sex for mystery, fun and romance. CBS came up with a successful variation in “Scarecrow and Mrs. King.� Now ABC is trying its hand at the formula with “Moonlighting,� a new series debuting Sunday at 9 p.m. (Channels 7, 3, 10 and 42).

While not without flaws, the two-hour premiere contains enough laughs, style and action to suggest that ABC has a shot at success too, although the regular time slot for “Moonlighting� will be Tuesdays at 10 p.m., opposite “Remington Steele,� the very show that inspired it. (Glenn Caron, creator and executive producer of “Moonlighting,� used to work on the NBC series, and the director of “Moonlighting,� Robert Butler, co-created “Remington Steele.�)

The “Moonlighting� story has Cybill Shepherd as a former model who, through unusual circumstances and with great reluctance, gets involved in a private detective agency that her business advisers had bought for her as a tax shelter. Bruce Willis co-stars as the fun-loving, irreverent head of the firm.

The pilot suggests the madcap style of a 1940s romantic comedy, but Butler and his actors occasionally seem to be trying too hard for the effect. In addition, Shepherd’s character lacks the proper degree of polish and sophistication for maximum contrast with her rude introduction to the world of crime, and Willis, evidently patterning his character on the Bill Murray screen persona of a brash, fast-talking, pseudo-hip Cool Guy, comes off as too callous and shallow to be completely likable.

There is a nice chemistry between them, however, and Caron’s writing is sharp, so that with a bit of refining, “Moonlighting� may turn into a welcome, if familiar, bit of prime-time diversion.
