Two dollar bill advocate (and interviewee for the film) Heather McCabe has been documenting the interactions she has with vendors whenever she spends a $2 bill. On her popular site twobuckaroo.com, she shares her experiences and also offers $2 bill news and other great information.

New York attorney Steven Reisman, who appears in the film and shares his thoughts on the $2 bill and the way it "makes the world a better place" was featured in an online article about his generous ways.

One of the coolest features in the film is the opportunity to see all of the $2 bills that have flown in outer space and hear the stories about them. But you can get a sneak peek at these bills by viewing the website where they reside
