This is such a great time capsule movie. You can smell the cigarette smoke when you watch it. It also has the most perfect ending shot I've ever seen.

One of the best action movies of that era, the 1970s. The actors are all first rate. Here's the IMDB link: https://www.imdb.com/title/tt0072251/ for those interested.

I grew up on Walter Matthau movies. He was such an unlikely action hero, but I loved watching him.
