Realizado por Mario bava e com a carismática Barbara Steele no papel principal, La Maschera del Demonio é definitivamente um marco na historia do cinema Italiano.
Visualmente hipnótico, um tanto teatral e definitivamente gótico este foi o filme que catapultou Mário Bava para a fama.
“‘One day in each century it is said that Satan walks among us. To the God-fearing this day is known as Black Sunday,’ a portentous voice has told us. Surely this is that day, and the face that glares at us from the screen, transfixed in a seeming ecstasy of evil, is Satan incarnate in bewitching mortal form. The glaring depths of her eyes radiate pure hatred, but strangely, this in no way obscures their beauty. A predatory joy in her savage expression imbues the pale visage with an inhuman quality. Her lips are thin, yet sensuous. Wild black hair frames the pale cheekbones. A study in chiaroscuro, her luminous portrait is delineated in shadows worthy of the brush of an unknown master. The exquisite face is cruelly marred by a pattern of wounds, impressed upon her flesh by the spiked mask she has worn for centuries.”
