Hello Down There

Hello Down There (rereleased in 1974 as Sub-A-Dub-Dub) is a 1969 American comedy-adventure film starring Tony Randall and Janet Leigh that was released by Paramount Pictures. It was produced by George Sherman and Ivan Tors and directed by Jack Arnold and Ricou Browning (underwater sequences). The screenplay was written by John McGreevey and Frank Telford. Plot Fred Miller must prove that his new design for an underwater home is viable by convincing his family to live in it for 30 days. His son and daughter are members of an emerging rock band, and they invite the two other band members to live with them during the experiment. Their temporary home, which Miller dubs the "Green Onion," is 90 feet below the surface of the ocean and is filled with modern appliances and amenities for housewife Vivian, all designed by Miller. A large opening in the floor provides direct access to and from the sea. The group are soon joined by a live-in seal named Gladys and a pair of dolphins that stay close at hand and fend off sharks. The family is confronted by many obstacles, including a rival designer from Undersea Development, Inc. who begins to cause problems. Meanwhile, the band's single has gotten the attention of record executive Nate Ashbury, who wants to sign them. He books them for a televised performance on The Merv Griffin Show without first communicating with them. After learning that they are living under the sea, he schemes to bring Griffin and the TV crew down to the Green Onion, but the navy is alerted to the sound of the music and becomes suspicious.
