The Criminality of Charley and Nadine
"Charley Varrick" is a great little movie...but it is a little movie.
Things happen plot-wise like a well-built watch, but director Don Siegel and his screenwriters seem content to "gloss over" certain plot points and just move along. They don't spend a lot of time exploring "back story" EXCEPT for plot: that Charley Varrick was once an airshow pilot who did a drunk act and could flip his bi-plane upside down; that he turned to crop-dusting to make a living and failed and that and then -- he became a bank robber? Located a psycho ex-Vietnam war vet like Andy Robinson's Harmon to work with? Found a tough guy like Al Dutcher(killed before we can meet him, in the botched bank robbery escape, but we're told he served prison time for killing his wife!).
And what about Nadine? Seems like a mature enough ol' gal, but when the cops start asking questions -- she shoots one point-blank in the face and the other in the gut.
In short, there seems a "disconnect" between how Charley and Nadine went from being air show performers to crop dusters to bank robbers...and exactly WHY Nadine(of all people) could be such a cold-blooded killer.
I suppose the cops had Nadine dead to rights, an arrest was imminent even as the bank robbery was in process. I suppose that Charley and Nadine figured cops just might have to be killed. I suppose Nadine made that call and took that action.
I also suppose the movie hints at what happened here:
Probably Charley and Nadine came from poor, hardscabble backgrounds. An airshow is rather like a travelling carnival, if not the best sort of air show, its like a low-rent circus.
And then Charley failed in crop dusting as "the last of the independents" against "the big combines"(he relates to Harmon in one of the film's few awkward exposition scenes.)
Harmon needles Charley about "is that what made you the big winner you are today?" and we see that Charley lives in a pretty small mobile home.
Hence, its just possible: Charley Varrick and his wife Nadine are among those "losers" in society who decide to get even.
As "Charley Varrick" proceeds, Nadine is dead(shot by the cops she shot) and Matthau is charming and smart and pitted against very deadly Mafia types...but we can never really shake the reality(especially when Varrick is played by funny Walter Matthau), that Charley Varrick's life story went so wrong along the way he decided to join the people who are willing to make a living by pulling guns on innocent others and taking their money. And killing them.
