Aided by loan money ear-marked for space travel research, the small Duchy of Grand Fenwick attempts to fly to the moon using wine as a propellant.

This comedy adapts The Mouse on the Moon novel to a two-act community theatre stage play. As the book was released when Mercury was still the spacecraft of NASA, it predates the Apollo flights to the moon. The premise of the adaptation is, what if the Duchy of Grand Fenwick did launch their rocket to the moon at the same time as Apollo 11?

Significant research into the Apollo 11 flight has gone into the writing of the script using little-known events from the actual flight. The staging assumes a community theatre or high school budget and cast.

Leonard Wibberley’s The Mouse on the Moon was originally published in 1962 as the sequel to the popular The Mouse That Roared. In 1963, it was adapted to a film staring Margaret Rutherford, Ron Moody, Bernard Cribbins, Terry-Thomas and David Kossoff repeating his role as Professor Kokintz. A Dell comic was released in 1963 as an adjunct to the movie.

While The Dramatic Publishing Company has a stage play for The Mouse That Roared, a stage play for The Mouse on the Moon called Mouse on Mars was only available briefly.
