Art Imitates Life
A few years before this movie was made (about 1975) a person dressed as Santa robbed a downtown Evansville, Indiana bank. They have never been caught and there has never been a suspect in the case. The Police have said that it was probably a woman, but they don't really know. The robber simply ran out of the bank with the money and disappeared into the crowd of Christmas shoppers.
As for this movie...I love it. I remember seeing a still of the murder in a magazine when the movie came out. But I never saw the movie, til I saw the movie on HBO and wow it was great.
I also love the slogans on the t-shirt of the big busted teller... very funny stuff. And Gould shows that he can actually act when he wants to. Plummer is just amazingly EVIl.
