Writer/director Ol Parker's debut takes its title from "Happy Together" by the Turtles ("Imagine me and you / and you and me") and its inspiration from the romantic comedies of Richard Curtis (Love Actually). There's a twist. Flower shop owner Luce (Lena Headey, The Brothers Grimm) is gay. Newlywed Rachel (a convincingly UK-accented Piper Perabo, Lost and Delirious) is straight. The two meet at Rachel's wedding--Luce designed the floral arrangements--and feel an instant connection. Rachel brushes it off.
