If you’ve ever looked into film noir, no doubt you’ve come across Double Indemnity. It’s often cited as one of the definitive examples of the genre. It actually transcends noir in my opinion and works effectively as a crime drama attracting a wider audience.
I won’t spend a lot of time focusing on the plot here, but if you’re not familiar it’s fairly simple. Walter Neff (played by the always likeable Fred MacMurrary) is an insurance salesman who one day by chance encounters Phyllis Dietrichson (in a noir defining role for Barabra Stanwyck). Dietrichson is married and the two go in on a plot together to murder her husband and collect the insurance money. As these movies usually go there ends up being a snag in the plan and everything begins to unravel.
