This 1964 sequel to the 1963 box-office hit Flipper is unnecessarily melodramatic at times but at least it isn't a cookie-cutter imitation of the original. Suzy the Dolphin returns to the "male" role of the superintelligent Flipper while Luke Halpin reprises the role of Sandy Ricks. This time Flipper rescues a British family in the Bahamas who are being held for ransom. Brian Kelly takes over from the first film's Chuck Connors as Ranger Porter Ricks a role he'd continue to play in the long-running (1964-67) Flipper TV series.
