Development The film was made by Hemisphere, an offshoot of Columbia under the supervision of
Mike Frankovich which shot films outside the US. They co produced with Todon, the production company of agent-turned producer Tony Owens and his wife, actor Donna Reed. It was originally named
Mark of the Leopard. It was then known as
Mombasa and
Black Mamba. It was the only one of Todon's British pictures to star Donna Reed, although she co owned the company. The film was to star
Aldo Ray but he turned down the role. As a result, Columbia put him on suspension.
Cornel Wilde replaced him in December 1955. A key support role went to
Ron Randell.
Shooting Filming took place in the studio in London and on location in Africa. It was to have begun in July 1955. Filming didn't start until February 1956. After the film was completed, Owen said all of his films "stink - but they made money." However he said
Beyond Mombasa "is the first one I've done that isn't lousy - and I'm worried." ==Reception==
