For his leading man, Disney chose Tom Tryon, who had been starring in "Texas John Slaughter" on television, but for the space female Disney chose Dany Saval, then touted as the "new Brigitte Bardot" for her American debut. He surrounded his two young stars with many experienced actors and a chimp for children. Disney's songwriters, the Sherman brothers, contributed several songs to the film with Saval recording "The Seven Moons of Beta Lyrae", which was released on a record with Annette's "The Crazy Place in Outer Space". (The complete song lyrics may be found on this article's "TALK" page.)
