Theatre of Blood (known in the U.S. as Theater of Blood) is a 1973 British horror comedy film directed by Douglas Hickox, and starring Vincent Price as vengeful actor Edward Lionheart and Diana Rigg as his daughter Edwina.

Plot After being humiliated by members of the Theatre Critics Guild at an awards ceremony, Shakespearean actor Edward Kendal Sheridan Lionheart is seen committing suicide by diving into the Thames from a great height. He survives and is rescued by a group of vagrants. Two years later, beginning on the Ides of March, Lionheart sets out to exact vengeance against the critics who failed to acclaim his genius, killing them one by one in ways very similar to murder scenes in the season of William Shakespeare's plays that he last performed. Before each murder, Lionheart recites the critic's damning review of his performance in the role. The first critic, George Maxwell, is repeatedly stabbed by a mob of murderous homeless people, suggested by the murder of Caesar in Julius Caesar. The second, Hector Snipe, is impaled with a spear, and his body is dragged away to appear at Maxwell's funeral tied to a horse's tail, replicating the murder of Hector in Troilus and Cressida. The third, Horace Sprout, is decapitated while sleeping, as is Cloton in Cymbeline. The fourth critic, Trevor Dickman, has his heart cut out by Shylock in The Merchant of Venice, the play being rewritten so that Antonio is forced to repay his debt with a pound of flesh. The fifth, Oliver Larding, is drowned in a barrel of wine, as is the Duke of Clarence in Richard III. For the next play, Romeo and Juliet, Lionheart lures the critic Peregrine Devlin to a fencing gymnasium, where he reenacts the sword fight from the play. He badly wounds Devlin but chooses not to kill him at this juncture. The sixth critic, Solomon Psaltery, an obsessively jealous man, murders his wife, believing her to be unfaithful, as portrayed in Othello. Although Psaltery survives, his actions lead to his imprisonment, and he will likely die in prison. The seventh critic, Miss Chloe Moon, is electrocuted to replicate the burning of Joan of Arc in Henry VI, Part 1. The eighth
