I've Gotta Horse (also known as Wonderful Day[2]) is a 1965 British musical comedy film directed by Kenneth Hume and starring Billy Fury, Amanda Barrie, Michael Medwin, Jon Pertwee and pop bands The Gamblers and The Bachelors.

It was one of several rock musicals from Nat Cohen at Anglo-Amalgamated, starting with The Tommy Steele Story and including Play It Cool (1962) also with Fury.

[6][7][8] According to Amanda Barrie, continuity on the film was poor because Hume would routinely throw out pages of the script if running behind schedule.

[7] The Monthly Film Bulletin wrote: "The line-up of songs and production numbers is unusually generous: sometimes there is only a brief snippet of dialogue or story development (not that there is, in fact, much of a plot) to separate them.

The dance ensembles are executed with precision, yet despite a general liveliness and even suggestions of imagination in the presentation, they lack that eye-catching exuberance and flair which one associates with Hollywood: somehow or other the polish does not create a real shine.
