LOSING CONTROL (opening tomorrow, March 23rd, at the Quad Cinema in NYC) is a romantic comedy about a female scientist who decides she wants scientific proof that her boyfriend is the One. Oh yeah, and her science lab day job involves studying an obscene amount of semen. But this is not semen-as-hair-gel slapstick stuff (although there is one tantric-propelled semen gag) — the science in this movie is actually pretty legit, because writer-director-producer Valerie Weiss happens to have a Ph.D. in Biophysics from Harvard Med School (she was also Em’s classmate at Princeton). Weiss founded the Dudley Film Program at Harvard, and while writing her dissertation, she directed her first film. Two weeks after wrapping production, she defended her Ph.D. thesis — and she hasn’t done another experiment since.
