William Forsythe, most recently snarling at G-men as Al Capone on Paramount Television’s “The Untouchables,” is making his leading man bid, toplining in the PM Entertainment romantic thriller “Direct Hit” for HBO Pictures.

Sources said Forsythe jumped in for the four-week shoot after thesp Steven Bauer left the project.

“Direct Hit,” which started shooting in L.A. last week, is described as the story of a CIA hit man determined to leave “the agency” after one last assignment. That final job turns sour after he falls for the intended victim, a reluctant stripper, played by Jo Champa.

Though cameras are rolling, PM reportedly is still looking for a thesp to play Forsythe’s crooked CIA boss. The film’s budget is estimated to be in the $ 1 million range, and the pic is being helmed by PM co-partner Joseph Merhi. Joe Hart wrote the script.

Sun Valley-based PM Entertainment, run by Richard Pepin and Joseph Merhi, just finished production of “CIA 2: Target Alexa” and the Stephen Furst starrer “Ninja Dragons.” The indie shoots about 12 pix a year.

Forsythe is repped by United Talent Agency’s Nick Stevens. “The Untouchables” has been renewed for the fall syndie sked.
