Lanky, blonde actor Luke Halpin is best remembered for playing responsible older brother Sandy Ricks in the popular 1960s outdoor adventure series Flipper. In the first Flipper movie, his character Sandy was, next to Suzy (the dolphin who played Flipper), the lead character. So it was early on in the 1964 series, but gradually Halpin's role was reduced in favor of expanding the role of his younger brother, Bud (Tommy Norden). Halpin made his acting debut playing a small role in the 1960 live-action version of Peter Pan. Following the demise of Flipper, Halpin's career became sporadic and his roles much smaller.
