Gidget Goes Hawaiian (1961) puts Deborah Walley in the title role. She's no Sandra Dee, but at least there are shots of Walley doing her own surfing stunts. The action's in Waikiki, and Gidge is pursued by a confused Moondoggie and a famous dancer. They are played by James Darren and Michael Callan, and having the two 1960s male ingenues in the same movie suggests a weird collision of matter and anti-matter. The spark goes flat in Gidget Goes to Rome (1963), with yet another new actress (Cindy Carol) paired with a loyal James Darren. It's closer to Three Coins in the Fountain than the sandy beaches of Malibu.
DVD caveat: none of the films is in widescreen. The sequels don't suffer much, but the original Gidget was shot in CinemaScope, and the pan-and-scan approach hurts the summery look of the picture--even if it's just Sandra Dee balancing in front of blue-screen waves. --Robert Horton
