MEL GIBSON is in negotiations to star in “Every Other Weekend,” an action-adventure project that will be directed by French filmmaker Benjamin Rocher.

    Clement Miserez and Jean-Charles Levy are producing the feature — which is eyeing a late-year start in France — along with Peter Safran (“The Conjuring”).

    The script has a multigenerational-family storyline that centers on a father who has his son convinced he’s a CIA spy, but in actuality he works in the agency’s IT department. However, on a father-son trip in Paris, the two find themselves in a life-threatening adventure in which secrets are spilled.

    Gibson will play the grandfather, who actually is a spy.

    Brandon and Curtis Birtell wrote the original script with revisions by Davis Moreau and Tad Safran.

    The actor is shooting period drama “The Professor and the Madman” with Sean Penn and enjoying strong buzz for “Hacksaw Ridge,” his first directorial outing since 2006’s “Apocalypto.” The war drama starring Andrew Garfield is due to be released Nov. 4.(SD-Agencies)
