The DVD package says this is "a sly & smart comedy", but I have to warn you, that's not exactly what you get. To me, a sly & smart comedy would be "Dirty Rotten Scoundrels" or "Deathtrap" or even "Fargo". While this movie has the same bizarre, criminal elements and intelligent dialogue as the above, I never sensed any outright comedy.
Still, it's well done & definitely worth a watch. Rather than a comedy, I would describe it more as a "drama of errors". The subject of murder is actually handled quite seriously although its casual nature might come across as odd (hence the humour?). There are no real laughs, but the strangeness of the story might elicit a few snorts, chortles, and possibly even a harrumph. But no guffaws.
The acting is excellent, the script is good, the style & direction is smooth & suave, like the 1940s setting it depicts. Some might consider it slow, but I'd say that's a plus because it gives us time to digest the complex themes that are presented such as the incompatible definitions of 'love', the value of loyalty in marriage as well as friendship, and of course the morality of murder.
Overall I liked this film. It's just the dag blasted ending that left me feeling cheated. I won't talk about it except to say that you should watch the alternate endings included on the DVD instead. In particular, Alternate #1 is closer to the book, and it gives us the thematic closure that the theatrical version omits. Alternate ending #1 also has a great piece of acting by Pierce Brosnan which, if it were in the actual movie, would've definitely made me bump up my rating by 1 or 2 stars.
"Married Life" is definitely worth the $2 rental fee. It deviates from the book on several key elements (such as the ending) and as a result doesn't quite wrap things up convincingly. But as far as movies go, it's entertaining, engaging and showcases some great acting talents.
