I have a lot of affection for the teen beach movies of the 1960’s starring the late Annette Funicello and Frankie Avalon, with guest stars including Buster Keaton and “Little” Stevie Wonder.  There was a nice update, “Back to the Beach,” and a knowing tribute to the genre in Tom Hanks’ “That Thing You Do.”  I am really looking forward to this week’s Disney Channel salute, “Teen Beach Movie,” premiering July 19.
