A follow-up and close cousin to the wildly successful Charade, Arabesque stars Gregory Peck and Sophia Loren in the Grant/Hepburn roles as an Oxford professor and a potentially untrustworthy femme fatale embroiled in a dizzying plot to assassinate a Middle Eastern politician. The first of three Donen films shot by cinematographer Christopher Challis, the film is awash in 1960s style, from the op-art camera effects to the chic moderne décor. Substituting a glamorous London for Paris, Arabesque ratchets the tension one step further than Charade’s often tongue in cheek suspense mystery with a series of visually thrilling action sequences—at Ascot, high atop a London bridge and, memorably, at the zoo—that never let up their exhilarating breakneck speed.
