British director Alexander MacKendrick helmed this farcical romantic comedy set in Southern California. Carlo Cofield (Tony Curtis) is a footloose tourist who meets Laura Califatti (Claudia Cardinale) when she accidentally edges his car off the highway. Laura invites Carlo to her home; he seems interested in her, but discovers she's already involved with swimming pool magnate Rod Prescott (Robert Webber). The next day, Carlo hits the beach and nearly drowns in the ocean, until he's rescued by comely sky diver Malibu (Sharon Tate). Carlo blackmails Rod into giving him a job so he can stay in California and pursue a romance with Malibu, but he soon finds himself torn between her and Laura. Don't Make Waves also features a theme song by The Byrds.
