Sure, there were dozens of con men films before it and even more after, but The Sting is the quintessential example. It has nearly all of the elements featured in a great con film, from the mismatched pairs to the long drawn con to the last-second double con, and all work together so well. But of course, The Sting wouldn't be what it is without the characters of Henry Gondorff (Paul Newman) and Johnny Hooker (Robert Redford).
Yes, their characters' names are Gondorff and Hooker but it's really Redford and Newman on screen. It's Butch and Sundance reunited! But, in all seriousness, both actors are pitch perfect in the roles and their con is so fun to watch play out that it's no surprise the film won 7 Academy Awards.
