"Reversible Errors" seems to have been a TV movie, based on the Scott Turow novel, and starring William H. Macy, Felicity Huffman, Tom Selleck, Monica Potter, and Shemar Moore.
The story concerns a triple murder for which one man, played by Glenn Plummer, confesses to a police detective, Larry Starczek (Selleck) and is condemned to death by a judge (Huffman) after a bench trial. It's a career maker for the young prosecutor, Muriel Wynn (Potter) having an affair with Starczek.
Fast forward to seven years later - the judge now works at a perfume counter, having been removed from the bench for taking bribes; Muriel Wynn is married and running for office; Starczek is still a detective; and Gandolf, one sandwich short of a picnic, is still on Death Row and now proclaims his innocence. He is assigned attorney Arthur Raven (Macy) who reluctantly looks into the case. The more he looks into it, the more confusing and messy it gets.
Complicated, strong story made even better by the team of Macy and Huffman, who are wonderful and on a much higher level than Selleck-Potter. Potter, with her flat delivery, has always reminded me somehow of Julia Roberts, and every time I hear her name I think of the old I Love Lucy episode when Ethel returned to her home town: 'Ethel Mae Potter, we never forgot her.' Selleck is handsome and comes across as a detective, but in actuality, this is a character role, and he's not a character actor. There's no spark between them. There is some very good acting by Plummer, Moore, and James Rebhorn.
I recognized several Canadian actors, so I guess this was filmed there.
I found this an involving story and one really becomes interested in the Macy-Huffman relationship. Recommended.
