An unusual movie/TV tie-in has been fashioned to promote Chevy Chase’s transition from the theatrical film wars back to TV as a talkshow host for Fox Broadcasting.

Chase, who got his start not only as a “Saturday Night Live” TV regular but as co-star of Ken Shapiro’s 1974 hit lampoon feature film “The Groove Tube,” will host the public service and policy trailers for the United Artists Theaters chain that admonish the audience not to smoke, talk, litter and the like.

Trailers will run starting Friday and continue through Sept. 9 at UA’s 2,300 screens, with Chase’s talkshow debuting Sept. 7 via Fox.

“We wanted to surprise and entertain our customers with this innovative policy trailer,” said Bill Quigley, UA senior VP of marketing.

“This is a huge kickoff for our campaign to build awareness of and anticipation for ‘The Chevy Chase Show,’ ” said Tracy Dolgin, exec VP marketing for Fox Broadcasting Co.

Chase is not abandoning cinema entirely, as he’s reunited with his “Fletch” director Michael Ritchie for the recently lensed “Cops and Robbersons,” an upcoming TriStar release co-starring Jack Palance.
