Impact

The interesting story and cast help to make this a good film-noir, with an involved plot that keeps your attention even through a couple of slower stretches. In the lead role, Brian Donlevy gives a low-key performance that works pretty well.

Donlevy plays a talented but rather naive businessman who suddenly finds himself the target of his scheming wife and her calculating boyfriend. The story passes through several different stages, as the whole story gradually comes out. It's structured so that the audience knows much more than any of the characters do, and thus much of the suspense comes from wondering how they will react if and when they figure it all out.

As the scheming wife, Helen Walker is solid in conveying her character's deceitfulness. Ella Raines is satisfactory as a resourceful woman who befriends Donlevy's character. Charles Coburn gets a good amount of screen time as a detective, and although much of the time his character serves only to advance the plot, Coburn makes good use of his occasional opportunities to do more. Mae Marsh only gets a handful of scenes, but she has one good speech in a scene with Donlevy. Anna May Wong plays a character who is important to the plot, but unfortunately the role does not give her much of a chance to display her considerable acting ability.

Aside from meandering a bit at times, the story works pretty well. The various pieces of the movie fit together most of the time, and it maintains the tension effectively. As a whole, it's somewhat above average, and it should not disappoint most fans of its genre.

Although the final third gets in the way and is finally disappointing,it does not keep "impact" from being absorbing and entertaining.One of the rare film noirs -maybe the only one - which takes a look on the brighter side of the road:sandwiched between two very dark parts,the second one has Capra accents:the country town is some Shangri-la where time stood still ,with its very nice people ,the girl who owns a garage but of course does not know anything about mechanics(woman's lib supporters will cringe),the young father proud of his new-born son ,the Sunday service,the old lady cooking tasty little dishes.All of this is unusual in a film noir.Some might say that "shadow of a doubt"(1942) had already that ,but evil could enter this world,as the heroine 's uncle came to town.Here,the evil is elsewhere ,in San Francisco.Only in San Francisco.Or on the dark road where anything can happen:first part is effective,and shows some "Postman always rings twice" (1946) influence.

This film noir has three distinct movements. Brian Donlevy proves masterful at playing a high-powered executive, self-satisfied and in control. As in any good drama, his secure world is assaulted and turned upside down The film portrays his characters descent, loss of faith and subsequent redemption. Donlevy handles each of the stages well.

Helen Walker is brilliant as Donlevy's wife. Her ability to portray a duplicitous and homicidal spouse is immaculate in it's delivery.

I found great pleasure in watching the legal machinations and the ambivalence of the justice system.

More then anything, and I've commented on this in other film noir reviews, I enjoyed the street scenes of San Francisco a half century ago. Sometimes I think I'd be just as happy to forgo plot in favor of travelogue Also, Larkspur (whether it is in California or Idaho,) just seems like a fine little town the likes of which we now pine for. The volunteer fire department scene was reflective of my sense of small town values.

All in all, an absorbing,nostalgic and thought provoking piece of film art.

A good example of a little known "film noir," this 1949 film was shot primarily on location in San Francisco.

There is good acting all around, from the main stars down to supporting cast, and the plot does tie together nicely.

Look for Mae Marsh, a silent film star who plays Ella Raines mother, and also look for a brief cameo appearance by syndicated columnist and radio personality Sheila Graham, playing herself of course.

Brian Donlevy, who made similar "noir" films, among them D.O.A., appears to be right at home in this film, and is wonderful in an understated way.

The film, at almost 2 hours in length was a bit long for the time, and might drag a bit, but is worth watching.

Anna Mae Wong plays the maid in this film, an old time character actress from the days of silent films, she has a small but all important role in the film, for she holds the key (literally) to how the whole movie ends. Listen for some degrading Chinese music when Ms. Wong is on the run.

Interesting note, Helen Walker who plays the scheming wife in the film, was involved in a major scandal of her own. On New Years Eve, 1946, she was driving home some hitchhiking soldiers near Redlands, California. Walker, apparently drunk at the wheel, got into a car accident in which one of the soldiers was killed and the other two badly injured. Though in the end exonerated of any guilt from the accident, it seemed to plague her for the rest of her life, and she slipped deeper and deeper into depression.

Whoever likes movies of the late Forties should not miss this one. It tells a typical film noir story that is coherent and easy to understand. Impact is a quite artful picture, obviously made by first rate professionals. The balance between location shooting (mainly in and around San Francisco) and the extraordinarily stylish sets is in my opinion perfect and well thought out. At the center of the story is the attempted killing of the main character by his wife's lover. The car with the two men drives at night along a sinuous mountain road. It slows down and stops because of a flat tyre. As the viewers already know, this is the spot where the murder should take place. With unbelievable ease the natural surroundings (reminding you of the dramatic climax in Hitchcock's Family Plot) change into an almost expressionistic stage set with artificial fog at the bottom and everything. It is an unforgettable moment. What the film people could achieve in those days!

Brian Donlevy has some very good moments. As after a phone call he fully realises that his wife who he naively loved (calling himself "Softy" in his messages to her) had cheated and betrayed him, he stumbles to a bench on a station platform, stares into the void with dim eyes and then starts crying with rage and frustration. The scene takes almost a minute and proves that Donlevy is a much underrated actor who should be honored more.

Apart from the realistic presentation of parts of San Francisco in the late Forties (it complements Welles‘ impressions in Lady from Shanghai"), Impact has some nice pieces of slang (at least to a foreigner whose mother tongue is not English). "Grovel a shuteye" for "taking a nap", that's nice, isn't it?
