It was directed by Eric Till and produced by Mildred Freed Alberg, from a collaborative screenplay by Ira Wallach and star Peter Ustinov.

He convinces computer programmer Caesar Smith to follow his lifelong dream of hunting moths in the Amazon Rainforest.

Assuming Caesar's identity (how he does this is not explained in the film), he gains employment at the London offices of an American conglomerate called Tacanco.

In a twist, it seems that a now-heavily pregnant Patty found the loose change from his foreign visits money and invested it in companies Pendleton mumbled about in his sleep, thus making a profit for Tacanco.

She persuades Klemper to rehire Pendleton as Taranco's treasurer: the reformed embezzler could easily spot fraud, and would not steal from his own company.
