I saw this in the theaters on the big screen in brilliant color. Unfortunately all that remains is a red DVD in my collection and a faded one on Y/T. The story moves along at a Bond-like pace with gadgets galore and sets not matched in many other imitation Euro-Spies. During the filming, they used many different European locations including the Baalbek ruins in Lebanon. Pier Angeli is her usual vulnerable self and Brett Halsey is the spy who figures everything out in the end. If you can find a good copy, watch it.
