Having just spent an entire day watching Walter Matthau movies, I can confirm that he can make a womanizing dentist likeable, a drunken deadbeat little league coach lovable, and an incorrigible shyster ambulance-chasing attorney downright adorable. But he can also pull another trick, which is to suck most of his natural humor and charisma out of his bone marrow but remain intriguing, watchable, and even magnetic. His Charley Varrick isn't the romantic kind of career criminal - he unapologetically works with violent killers, and he's not saving up to get his kid brother an operation. He, like the men in many Siegel films (including this one), is just doing his job. He's smart, though, and that gives him a fighting chance, provided he can stay smart and broke rather than dumb and rich. A lesson for us all!
