Gypo Nolan (Victor McLaglen) is as poor as anyone on Earth. Living in 1920s Ireland, Gypo and his fellow Irishmen are part of an underground rebellion against the oppressive Brits. One particular rebel, wanted for murder by the English, arrives back into town secretly. He thinks he can trust his friend Gypo, but the £20 reward proves too tempting. Gypo gets his friend killed and sinks into a pit of despair and drunkenness. Meanwhile, the other Irish rebels are searching for the informer. Right away, Gypo, with money burning a hole in his pocket, is their main suspect, but they, who are his friends, don't want to believe it. The story of The Informer is simple in its plot, but complex in its moral and emotional issues. It's easily one of John Ford's most emotionally involving films. What Gypo did was wrong, but we can certainly understand his motives. We also understand his sorry character, and there's a lot of sympathy that arises for him. The script is very suspenseful, as well. It's the kind of suspense where we are pretty sure we know how everything will end up, so we have to grit our teeth and bear along with it. The acting is remarkable. Victor McLaglen, who acted in many of Ford's films, probably gave his best performance here (and won an Oscar for it). Every other performer in the film deserves his or her kudos. In addition to an amazing script and acting, The Informer is one of John Ford's most expressionistic films. I love the darker side of Ford. In its mood, as well as in its themes, The Informer reminds me of two of my other favorite Ford films, The Long Voyage Home (1940) and The Fugitive (1948); it's also a bit similar to The Grapes of Wrath (1940) in these respects. 10/10.
