Formula for a Murder

'7 Hyde Park – The Cursed House') is a 1985 Italian giallo film[2] co-written and directed by Alberto De Martino.

When it was released in Italy, it war marketed as a more traditional horror film, while retrospective analysis compared it to 1960s thrillers such as Taste of Fear (1961).

Joanna begins to experience hallucinations in which she sees a leering priest stalking her while holding a bloody doll in his hands.

[3] Historians and critics Adrian Luther-Smith and Roberto Curti both pointed out that the film closer resembled the Hammer production Taste of Fear (1961) more.

[3][1] Historian Troy Howarth echoed this statement saying that the film "harkens back to the "women in peril" thrillers of the 1960s" and "does not enter into the excessive spirit of the other gialli of the period.

"[1] Curti stated in his book on Italian giallo that the film exposes its villain early at the half an hour mark and that David Warbeck "hams it up shamelessly" towards the third act, resembling a "Jack Nicholson-wannabe".
