A romantic comedy about vibrators? No, we’re not talking about the third Sex and the City movie. It’s Maggie Gyllenhaal and Hugh Dancy’s upcoming film about Victorian doctor Joseph Mortimer Granville’s invention of the electronic implement that shall not be named. In the just-released trailer, Dancy’s character seeks a way to, ahem, relieve his female patients of the titular affliction. One deconstructed feather duster and a hundred or so volts later, he’s invented an at-home remedy for the ages.

Jonathan Pryce, Rupert Everett, and Felicity Jones also star in the film, which will premiere at the Toronto International Film Festival this September. See the full trailer after the jump.
