Although not the first screen appearance of Simon Templar, this film is based on the very first Saint novel.
First and only film in RKO's Saint series to feature the character of Patricia Holm, who was Simon Templar's recurring partner and love interest in the novels, and who was introduced in the book upon which this film was based. Also the only film to feature Templar's butler, Horace (named Orace in the books), who also appeared in several of the early Saint novels.
The novel's original title, "Meet the Tiger", made no mention of the Saint.
The eighth of nine classic RKO movies featuring Simon Templar, The Saint.
The £1M in gold at the time would equate to nearly $55.5M in 2016 - not accounting for the underlying value of the gold.
