The Seventh Floor (1967)

In this unusual offbeat black comedy directed by Ugo Tognazzi, Giuseppe (Tognazzi) is a middle-aged industrialist obsessed with gadgets. When his nose starts to whistle uncontrollably, he checks into a clinic to resolve the problem. What begins as a minor affliction worsens, and Giuseppe is placed on a different floor as his ailments multiply. The sicker he gets, the higher he goes up in the floors of the clinic, until he is near death's door.
