"Caesar Must Die" is not the name of a "Spartacus" spin-off.(which I'm also not entirely ruling out by the way) Rather, it is a riveting production of Shakespeare's "Julius Caesar," which is about power and betrayal, performed by a group of convicted criminals in a maximum security prison in Italy.(Of those we meet in the auditions, only a couple are not in their 40's, thus implying these are lifers in more than one sense.) This is not just a filmed stunt, as the claustrophobic environs of the prison are woven seamlessly and subtly into the performance itself, filmed in black and white. Ostensibly, these are just rehearsals which end up taking on a life of their own, as work on the theatre continues. Otherwise, the only segments in color are the play's ending and its triumphant aftermath. As much as the convicts put into the play via their unique interpretations, it could also be said that they get an equal amount out of the experience, as one comments at the end of the movie that after realizing that there is such high art, his imprisonment has become that much harder to bear.
