This film was based on Charteris’s story The Million Pound Day.
One thing you have to say about this movie - it doesn’t waste any time. It plunges straight into the action. For anyone not familiar with the character it also very quickly establishes Simon Templar’s personality as a quixotic hero who is chivalrous, determined and not very concerned about legal niceties when it comes to hunting down the ungodly.
The plot begins to thicken when Simon rescues an old fellow who is being pursued by a very nasty looking thug. Simon and Penny (Sally Gray) find that they have stumbled onto some kind of currency fraud. Penny being a young lady who has appointed herself as Simon’s assistant crime-fighter. Young ladies tend to do that sort of thing to Simon.
Simon’s old adversary Inspector Claud Teal of Scotland Yard (Gordon McLeod) is on the case as well and this time he’s easily persuaded that it would be better to work with Templar rather than against him.
Simon has acquired another assistant as well, a rough diamond American ex-con named Dugan (David Burns).
Sanders is in top form and he gets good support from the other cast members. Sally Gray makes a delightful heroine, always trying to get herself more involved than she should but in such a charming way that the Saint can hardly object. The villains are clever and ruthless and they’re more than just cheap hoods - they’re just the sorts of evil-doers the Saint enjoys matching his wits against.
The British all-region DVD release from Odeon provides a good transfer without any extras.
Even Leslie Charteris liked this movie and he was notoriously difficult to please when it came to movie and TV adaptations of his work. The Saint in London is a well-crafted B-movie thriller. Highly recommended.
