Donald Sutherland has said that Peter Bart’s forthcoming account of having witnessed the shooting of the legendary Don’t Look Now lovemaking scene, and observing that Sutherland and costar Julie Christie were actually doing it, is “mendacious.” Which is a roundabout way of saying Bart is full of shit.

But maybe he isn’t.

Bart’s tale is included in a new book he’s written titled “Infamous Players: A Tale of Movies, the Mob, (and Sex).” It streets on May 3rd.

“Not true…none of it…not the sex…not him witnessing it,” the 75-year-old Sutherland told N.Y. Daily News reporter Soraya Roberts in a story posted today.

Clearly, someone is either lying or greatly exaggerating or suffering from a faulty memory. Or is getting old. Sutherland was 36 or 37 when the Don’t Look Now scene in question was shot. Christie, currently 70, was 31 or 32 at the time, and Bart, now 78, was 40 or so.
