33:20 The murder of Mike and Melanie has been cut in the UK version. We only see Mike getting hit with the knife the first time and then Melanie starting to scream. What is missing is the murderer slicing Mike's back with the knife several times until he dies. Blood splatters, also onto Melanie's face. She does not stop screaming. After she got pulled out of the frame we see Mike's dead body.
