What I would do for a modern day sequel.
Sally Field, the TV Gidget, and James Darren, the movie Moondoggie Jeff Matthews, would be cast as Francis and Jeff Matthews. Their children would have been killed in a car accident and they are raising their granddaughter, Francie Matthews in Malibu, California. I would hold tryouts for the roles of Francie and the boy, certainly closer to her age, she falls for, and do publicity around this (like they did for Scarlet O'Hara in Gone with the Wind. I'd make the grandparents as hip as Gidget's parents were in
Gidget Goes Hawaiian. I'd give James Darren a chance to sing. As Gidget, Jr.'s friends I'd cast known teen actors. I'm a little out of touch regarding today's stars so suggestions would be appreciated.
