Problem!

Rating: 9/10 (18 April 2017)

Although the film is set in Maine, the Ohio State Reformatory in Mansfield, Ohio stood in for Shawshank Prison. The structure was slated to be torn down, but the production delayed its demolition for a year. After the film wrapped, all the buildings in the complex were torn down except the cell block and main administrative building, which were preserved for historical purposes.
That's why I give it a 9, not a 10.
Just joking. I'd give it a 9 any old day. I never give 10s.
