Unlike James Bond, the equally debonair Saint never made a successful transition to film from the fictional works of Leslie Charteris. Charteris hated all the film Saints - George Sanders, Hugh Sinclair and Leslie Howard. He thought that Cary Grant was the ideal choice for the role. But in the 1940s, the film industry would only make B-movies featuring the Saint. Since Cary Grant did not appear in B-movies, George Sanders got the role. He was popular in it at that time. Sanders always played suave cads extremely well. The Saint of the novels was also a suave cad, yet his creator did not approve of George Sanders. Charteris probably disliked Sanders because the latter did not physically resemble his creation. Roger Moore, the Saint of the small screen, came much closer to Charteris' ideal.
"The Saint's Double Trouble" is worth watching if you are Saint fan. If you like the sneering, sardonic George Sanders like I do, you will like it.
