As for the movie itself... For a 1936 suspense thriller, it holds up pretty well. Hitchcock fans won't want to miss it. There is a lot of humor in this film, most of it courtesy of Peter Lorre, who steals the film as the General.
This edition of the film runs about 86 minutes. I have seen video guides list the film as having a 93 minute running time. I do not know if this version is incomplete, or if there is in fact a longer version available somewhere. It wouldn't be the first time Laserlight has released a cut version (Hitchcock's "Jamaica Inn" was released with several minutes missing). Maybe a future reviewer can shed some light on this mystery.
The homely and genteel John Gielgud plays an English author whose death is faked during WW1 to set him up as a reluctant spy under an assumed name. His mission is to proceed to Switzerland to uncover and thwart a German agent. The beautiful and enthusiastic Madeleine Carroll is playing his wife. Gielgud meets her in a hotel where she is conversing with a very youthful looking Robert Young. Gielgud and Young eventually will vie for her affections. Gielgud is aided by a horribly miscast Peter Lorre. Lorre pays a phony Mexican general complete with curly black hair, a gold earring, prosthetic teeth and a terrible accent.
After killing the wrong man, Gielgud and Carroll show remorse and attempt to give up the spy game. The unsympathetic Lorre coaxes Gielgud to continue to pursue the real villain in a memorable scene in a chocolate factory.
In summation, Hitchcock has done a far better job with similar subject matter in 39 Steps, Saboteur and Foreign Correspondent.
