Geluk (2005)

In this film with its humorous undercurrent, a widower rents the upper floor of the house of a young couple, who can no longer afford the mortgage after a dismissal. The man immediately moves in. The only thing he brings with him - hidden under a cloth - is a large cage. Acting against the man's express warning, the couple goes up to his room when he is away. Their curiosity costs both them and the tenant dearly.

Unfortunately the movie Geluk is not yet available on HBO Max.
