Hold On! is a 1966 musical film directed by Arthur Lubin and starring Peter Noone, Shelley Fabares, Herbert Anderson, and Sue Ane Langdon. The film features performances by Herman's Hermits and stars the band as fictionalized versions of themselves. The soundtrack was released as an album, also called Hold On!.

When the children of American astronauts choose "Herman's Hermits" as the "good luck name" of the next Gemini space capsule,NASA scientist Edward Lindquist is sent by U.S. State Department official Colby Grant to shadow the band on tour. His orders are to find out all he can about them to stave off a "P.R. nightmare". (Grant fears that putting the band's name on the rocket will make the world think the U.S. is "still a colony of Great Britain".)

Aspiring starlet Cecilie Bannister hires a publicity agent and photographer to take photos of her with Herman and the band, sure that this publicity boost will get her a new contract with a movie studio. They take an unflattering picture during a riot of teenage girls at Los Angeles International Airport but the misleading story in the newspapers leads Lindquist to believe that Bannister is an "old friend" of Herman's. Likewise, Bannister believes that Lindquist is a writer and part of the band's entourage as they pump each other for information about the band that neither of them really has.
