There's not much more to say here other than that there's nothing that beats a good heist film. While some may quibble with my inclusion of 11 Harrowhouse on this list, I remember taping it off of cable when I was in my teens and watching it several times because even good to mediocre heist films are great even on repeat viewings. I'm not sure why people dislike 11 Harrowhouse so much, but I'm going to look at it again to see if it matches my memory of it. I'd appreciate reactions to it in the comments section.
In any case, there are some obvious omissions from this list (Rififi, for example) but I focused on those films that are currently available on Netflix Instant View. Hopefully doing this list will inspire me to finally catch up with The Hot Rock, which is often mentioned as an underrated film of the 1970s, and cited by Steven Soderbergh as an influence on his Ocean's Eleven.
The Italian Job (Peter Collingson, UK, 1969, 99 minutes)

Incarcerated criminal genius Mr. Bridger (Noel Coward) helps Croker get financing -- from his jail cell. Netflix link.
Topkapi (Jules Dassin, USA, 1964, 119 minutes)
