The Man Inside is a 1958 British crime adventure film directed by John Gilling and starring Jack Palance, Anita Ekberg, Nigel Patrick, Anthony Newley and Bonar Colleano.

[3] Sam Carter is a jeweller's clerk who dreams of stealing a fortune in diamonds and eventually does so, but he kills a man in the process.

He then embarks on the high life, but is pursued across Europe by private detective Milo March, a woman named Trudi Hall, and two thugs, Martin Lomer and Gerard Heinz.

[5] In October 1957 filming for the project was pushed back from November 1957 to April 1958 in order to allow for Warwick's challenged cash flow following the box office disappointment of Fire Down Below [1957].

With Anthony Newley as a Spanish cabbie, Donald Pleasence as an organ grinder and Sid James as a wideboy, the cast alone makes this worth watching, even if the plot is as old as the hills.
