After 'Shawshank' Escapee Appears in Court, A Look inside the Historic Prison Where the Movie Was Filmed

David Sweat appeared in a Plattsburgh, New York courtroom on Thursday to be indicted on charges connected with the breakout.

With his arm in a sling from injuries he sustained when cops shot him during his capture, Sweat quietly entered the courtroom and entered a plea of not guilty.

Sweat, who is already serving a life sentence for murder, faces charges of escape and promoting contraband.

His escape from Clinton Correctional Facility earlier this year reminded many of the classic movie, The Shawshank Redemption.

The movie was filmed inside a real prison - and INSIDE EDITION was allowed to bring our cameras inside for a private tour.

The film was shot at the Ohio State Reformatory more than 20 years ago. But today, the paint is peeling and there are cobwebs and rusty cell bars.

The prison opened in 1896 and closed its doors in 1990. Some of Ohio’s most dangerous criminals were held there.

Prison historian Scott Sukel told INSIDE EDITION: “Rapists, murderers, child molesters, you name it” were inside.

The prison made a perfect backdrop for Shawshank. The brackets that held the movie cameras are still on the ceiling.

Tunnels were made especially for the movie's classic scene where Tim Robbins' character made his escape.

Sukel said: “They had it filled with a mixture of chocolate syrup, candy bars, crackers and leaves to give it that sewer feel. For a few years it still smelled of chocolate.”

It looks like time has stood still in this prison, forever immortalized in The Shawshank Redemption.
