In classic English style, the main character's ironic wit pervades the entirety of this film as he commits a number of self-serving murders and romantic manipulations. This is what places Kind Hearts and Coronets firmly within the realm of black comedy while still retaining a suspenseful edge, a credit to the director's skill. The deranged yet self-assured Dennis Price as Mazzini brings a sense of cold charm to all the scenes, preventing the film from becoming too silly or disturbing.
