Adolfo de Jesus Constanzo, a drug dealer and cult leader who practiced ritual animal sacrifice during the 1980s, inspired the film. It was thought his voodoo spells were responsible for the success of the drug cartels he supported.

One expert, Patrice Faye, followed the horrific path the crocodile had left in its wake. He discovered the remains of 17 people on the trail, some of whom were fishermen and bathers.

In 1970, a student nurse named Donna was given the doll for her 28th birthday. A Raggedy Anne Doll, rather than the porcelain one seen in the film, it seemed to have a mysterious power hanging over it.

Donna’s roommate was the first to notice something strange about the doll. During the day, it seemed to change positions, sitting upright one minute, kneeling the next. Sometimes it would even move to other rooms. The doll attacked Donna’s friend, one night it glided up his body and attempted to strangle him.

Donna called in a Medium, who claimed the spirit of Annabelle Higgins, a 7-year old girl who had died in the apartment, possessed the doll.

In 1972, a group of Canadian students embarked on what became known as the ‘Philip Experiment.’

The students invented the character of ‘Philip’ and created a tragic back-story for him. They conducted a fake seance, and as they had hoped, a spirit latched onto the character and communicated with them. Despite calling itself ‘Philip,’ the spirit couldn’t answer any questions about him. It did have knowledge of real historical events, however.

The experiment was inconclusive. Had a real spirit been summoned or was it a manifestation of the groups subconscious? Was it mental phenomena rather than a spiritual one? Footage of the seance is available to view online.

In 1950, two police officers witnessed something that looked like a parachute falling from the sky. On locating the object, it turned out to be around six feet in diameter, purple, crystalline and jelly-like.

The ‘blob’ spent 25 minutes on Earth. We will never know if its ultimate goal was to eat mankind, as it sadly evaporated when the police officers tried to lift it. Only a sticky residue remained on their fingers, the last indication of this strange phenomenon from space.

Similar ‘blobs’ have fallen to Earth since, landing in Scotland and the Lake District in Cumbria, England. One man claimed to have come across ten ‘blobs,’ all floating on puddles and as big as his foot. He thought it might have been residue from frog spawn. Scientists have named it ‘Star Jelly.’ They think the ‘blobs’ probably came down with meteor showers. As yet there are no definite explanations for the jelly-like substance.
