Hello Down There' was a fun, campy adventure. The movie was a cross between `Lost in Space' and the `Partridge Family' but with lots of water, a predecessor of `Sea Quest DSV'. The plot was about a family who lived at the bottom of the ocean and the adventures and friends they made, both human and aquatic, specifically a dolphin. The songs were lively and fun for kids to sing. No `R' rating here. Several well known stars participated in the movie, such as Ken Berry, Richard Dreyfuss, Merv Griffin, Janet Leigh, Roddy McDowall, Lee Meredith, Charlotte Rae, and Tony Randall. I find `Hello Down There' to be a fond, fun memory from my childhood, and would love to see it released on DVD as a family classic film.
