One of the highlights, or lowlights, of this weekend’s TFF will certainly be the world premiere of “Ticked Off Trannies With Knives,” Israel Duva’s revenge fantasy featuring such sure-to-be-indelible characters as Bubbles Cliquot, Tipper Sommore, Rachel Slurr and Emma Grashun. And Pinky La’Trimm. Already, the film has caused a tsunami of vitriol on Tribeca’s Web site: “To make the attacks and murders of transgender women into a form of stupid entertainment is beyond unenlightened, it’s offensive and ultimately sexist,” wrote Anna R. “Tribeca Film Festival should be ashamed of yourselves for presenting this!” All this, and for a film that has yet to premiere. The fact that there’s so much pre-emptive venom when no one has actually seen the movie will undoubtedly make it one of the hottest ticket at Tribeca. We can’t wait to cross the picket line.
