Now in its fifth week, our summer movie series Tribeca Film Presents continues this Friday at 10:00 p.m. on MSG Network with Alex Karpovsky's 2012 DIY indie meta-comedy Red Flag.

Girls fans might be surprised to know that Karpovsky, who plays Greenpoint grump Ray on the hit HBO series, is also an indie writer-director, who stars in this movie as an indie writer-director named... Alex Karpovsky.

Newly-single and recently-wrapped on his latest project, self-absorbed filmmaker Alex hits the road with an old friend (Onur Tukel) to promote the film across the country, all while contending with half-empty theaters, a worshipful fan (Jennifer Predinger) who quickly drives a wedge between the two friends, and an endless string of increasingly absurd and totally exasperating personal humiliations.
