Mark of the Phoenix is a 1958 British second feature ('B')[2] drama film directed by Maclean Rogers and starring Julia Arnall, Sheldon Lawrence and Anton Diffring.

A newly developed and valuable metal is stolen and formed into a cigarette case for transportation to East Germany, but an American jewel thief comes into possession of it and finds himself a target.

The Monthly Film Bulletin wrote: "This spy story has all the usual trimmings as tough, handsome American jewel thief, portly art-collector gang leader, shot scientist, secret formula and brutal foreign agents as but almost makes up for their familiarity by lively pacing.

This turns out to be the film’s sole virtue, however, since direction, dialogue and performances are on a distressingly amateurish level.”[4] Picture Show wrote: "There's plenty of action in this exciting spy drama ... Sheldon Lawrence ably plays the confident thief and Julian Arnall supplies the slight romantic interest.
