Jack and Tom are cell mates. Their fragile bond begins to unravel when Jack falls in love with a black plastic bag.

The Green Mile is short on complexity and long on... well it's just very long. (three hours). Set in a Louisiana penitentiary during the Great Depression, The Green Mile, based on Stephen King's novel, is a story of death row inmates and guards. The film's title is the term used for the walk from an inmate's cell to the electric chair, nicknamed "Old Sparky".
The protagonist is Paul Edgecomb (Hanks), the head guard. Having walked the mile numerous times and witnessed more deaths than one man ever should, Paul has the respect of most of the inmates and offers whatever dignity he can, especially in their final hours. Paul forms a special relationship with one inmate in particular, John Coffey (Michael Clarke Duncan) who possesses magical healing powers.
The two villains are vigorously portrayed: a sadistic, craven guard (Doug Hutchison) and a strutting, rabid inmate (Sam Rockwell), whose crimes are even worse than we feared.
At the core of this movie though one finds a slacky, sappy film. The human misery that breathed so easily in Shawshank Redemption (same writer & director) is often forced here.
