The master of Italian horror, Lucio Fulci, stars as... Lucio Fulci, a filmmaker with a reputation for gruesome horror films. His body of work has started to plague his mental state, and he is haunted by the grotesque set-pieces his mind has conjured up during his career. His psychiatrist, Egon Schwarz, uses a hypnotised Fulci as an avatar to carry out his own disturbed fantasies, in hopes of ruining the master’s reputation once and for all.
Unfortunately the movie A Cat in the Brain is not yet available on HBO Max.
