If I hadn't paid attention to the opening credits, I never would have guessed that this was directed by Cecil B. DeMille. For years, I have disliked his films (particularly those made in the sound era)--mostly because his epics all seem to have cool special effects but also lag way behind the average film when it comes to characterizations. In other words, the films look good but often the dialog is silly and the characters very under-developed. However, unlike films such as THE TEN COMMANDMENTS or REAP THE WILD WIND, this one had a lot of heart and was an excellent picture in all respects. Sure, the special effects and cinematography were great (really great), but it didn't surprise me that the sets looked like Java--after all, it's DeMille. But for once, the supporting characters were rather three-dimensional and the only complaint I have about any of them is Loraine Day. Her character and how it was integrated into the plot didn't seem to work very well--but this is a very, very minor quibble.
Gary Cooper plays the title character. He also starred in two other DeMille films, THE UNCONQUERED and NORTHWEST MOUNTED POLICE, though I think he was best in this film because his part was a little more subdued--creating a quiet strength instead of the usual macho hero (probably because Dr. Wassell was a real person). This doctor was one of the last to try to vacate Java when the Japanese invaded in 1942 and the film was intended as a propaganda piece to encourage Americans at home and abroad due to the heroism in the story. Along with Cooper is a fine ensemble cast of supporting characters. And, thankfully, these supporting characters generally were not just cardboard stereotypes--a definite plus over some other similar films from the period.
All in all, it's an interesting film that's worth your time and an excellent example of the type of films DeMille could do had he chosen to focus more on people than special effects and spectacle.
