After filming wrapped, the cast and crew later remarked upon a number of supernatural experiences while filming on location in Italy. Alfred Molina reportedly felt an ice-cold hand grasp the back of his neck on a night-shoot, while Miranda Richardson felt her knee-high dress being aggressively yanked to the floor while waiting to film in an old castle. There were also several instances of crew-members having to leave the set after suddenly feeling unwell.
