This is a very enjoyable movie, especially for fans of Stephen Boyd and Yvette Mimieux. It isn't grim or gloomy or dark; it has that polish and cheerful charm that distinguished a number of fine 1960's films, such as Charade, Arabesque, Our Man in Marrakesh and The Prize. It may not be quite at the level of the best of those, but it was made in the same spirit: some adventure, a handsome leading man and lady, but without the huge, over-the-top effects, big budgets and set piece scenes of the James Bond movies, with which other films such as this could not compete.
Fans should know that as of now, there is both a Blu-ray and dvd available of this movie. This is especially welcome news for Stephen Boyd fans! Boyd is very good in his role here and is a pleasure to watch. This is a classy movie worth seeing.
