Keanu Reeves and director Francis Lawrence claimed "supernatural forces" had disrupted the shooting for a vital scene in "Constantine".

According to the filmmakers, the cast and crew who had gathered in sound stage 16 at Warner Bros' Hollywood studio were soon desperate to leave when "paranormal activity" allegedly started to arise in the building, the Internet Media Database reported.

"It was strange. We'd built theses two rooms, the physiotherapy and hydrotherapy rooms - they're a huge part of the ending of the movie. And one half of it, the physiotherapy side, just got weird," Lawrence said.

"We were there for six weeks in this room and people were getting sick, or didn't feel good or got angry. There was just something about that room."

It was particularly terrifying for all present - because they were all aware of the spooky forces that had tormented moviemakers working on "The Exorcist" and "Poltergeist".
