So what if she didn’t win the Oscar for editing Martin Scorsese’s Hugo? Thelma Schoonmaker already has three such awards for cutting his movies in a partnership now extending past its third decade. Scorsese also introduced her to her late husband, English director Michael Powell (1905–1990), whose Peeping Tom she’ll introduce tonight. The 1960 horror-shocker is often considered, along with Psycho, the progenitor of the modern serial-killer flick. The movie follows a meek London photographer (Carl Boehm) as he endeavors to capture the face of fear on his victims. (Watch out for that pointy tripod!) Wildly decried upon its release, Peeping Tom is often credited with killing Powell’s career, though the truth is more complicated than that. As part of her Q&A, Schoonmaker will tonight discuss her husband, how explicit violence was elided via editing in Peeping Tom, and probably dish a little dirt about the Oscars and Hollywood in general. (She also appears at Scarecrow Video at 2 p.m. today.) BRIAN MILLER
