IT’S easy to see what attracted Michael Keaton and Brendan Fraser to Michael Caleo’s “The Last Time,” which allows them to spout reams of faux-Mamet/LaBute dialogue as a pair of misogynistic salesmen behaving badly.

Keaton is a nasty, cynical old shark at a Westchester firm selling unspecified products, and Fraser is a wide-eyed go-getter from the sticks who flails badly when he arrives on the scene. But the situation begins to reverse when Keaton starts sleeping with Fraser’s wife (Amber Valletta).

Despite solid contributions by vets such as Michael Lerner and Daniel Stern, Caleo isn’t able to sell “The Last Time” – not the affair (the pair first have sex next to the passed-out Fraser) and especially not the ludicrous twist ending.

THE LAST TIME
