Paranormal Activity has surpassed The Blair Witch Project to become the most profitable movie ever made.
The film, directed by Oren Peli on a budget of $15,000 (£9,059), beat Saw VI to top the US box office last weekend and grossed $62.4m (£37.9m) in its fifth week on release.
It has now made $65.1m (£39.5m) and has reaped a 433,900% return on its initial investment for Paramount Studios, The Wrap reports.
