MCA TV’s “Universal Action Pack,” a weekly series of 24 primetime rotating telepix from top-line action producers, got off to a strong start in a dozen metered markets on Monday and Tuesday.

The first series in the “Action Pack” lineup, exec producer William Shatner’s “TekWar,” generated huge ratings and percentage increases for stations.

The premiere episode, the only one of the four that Shatner directed, pushed the weak KOFY in San Francisco 350% above its November average to a 5.4 rating/9 share.

Although KOFY posted the largest percentage increase, Tribune-owned WPIX-TV in New York Tuesday earned the biggest ratings with an 11.7/17.

On Monday, KPLR in St. Louis grabbed an 11.2/16, a 129% improvement from November.

“TekWar” also exceeded all two-hour premieres from last season on WDZL in Miami, where it finished with a 9.1/13 (225% above November).

The “Action Pack” consists of four episodes each of “TekWar,””Bandit, “”Vanishing Son,””Hercules” and “Fastlane” (working title).

MCA initially planned to produce four episodes of producer-director Rob Cohen’s “Midnight Run,” but the order was cut to three when star Christopher McDonald got a chance to appear in a feature. Cohen has produced “Knight Rider 2010,” a two-hour telepic that will air in its place.
