Venom

Venom (2005) is an American horror film you can watch online on iFILM. Director Jim Gillespie — known for I Know What You Did Last Summer — sets this one deep in the Louisiana bayou, where a voodoo ritual goes wrong and something worse than a ghost walks out of the water.

Ray stops to help an old woman whose car is going over a bridge. Her luggage holds snakes used in a local ritual to drain evil from bad people and trap it inside the animals. The snakes bite Ray. He goes into the river. When he climbs back out, the evil that had been accumulating in those creatures for years is now wearing his body. Agnes Bruckner, Jonathan Jackson and Laura Ramsey are among the teenagers left to deal with what he has become.

It is a straightforward slasher — no hidden metaphors, no twist that reframes everything. What it does have is a genuinely oppressive swamp atmosphere and a monster with an actual origin story behind it. Stream Venom (2005) online on iFILM.
