I’ve never thought of Gwyneth Paltrow as a particularly funny person.

Yet she has co-written and co-directed one of the funniest movies you’re likely to see all year.

Dealbreaker, co-written and co-directed with Mary Wigmore, is only 10 minutes long. But it packs some raucously laugh-out-loud moments into its spare running time and, in lead actress Arija Bareikis, has someone who knows all about comic timing.

Bareikis plays a sophisticated young Manhattanite who has dated and broken off with a long string of guys. As one of the subjects of a documentary film about ``serial daters” made by her current boyfriend’s best friend, she talks about the ``dealbreaker” in each of her broken relationships: that one moment when she realized the guy she was fond of was definitely not the one for her after all.

“After dating a while,” she says during her interview for the documentary, “their guard comes down.” It is in those unguarded moments that she can discern the true essence of the individual — whether the man is rude to a waiter or professes his love for an unacceptable-to-her music group — that squashes her interest. We see several of these dealbreaking moments.

All this builds to a hilarious sequence set in a bathroom with the young woman in the midst of a bubble bath when her boyfriend — the one she thinks is finally The One — enters and does something totally outrageous. You may be on the floor rolling with laughter as this dealbreaker unfolds.

Paltrow and Wigmore get to the heart of the matter with no holds barred and with a minimum of dialogue. Bareikis acts out the expectancy and horror she feels with eye movements and wonderful facial expressions. It’s wild!

Dealbreaker will show as part of a 90-minute collection of short films starting at 4:30 p.m. tomorrow at the Columbus Theatre Cinematheque, 270 Broadway, Providence.
