In this episode of Film Stories with Simon Brew, two films that hit much bigger than expected - each of which changed a lot in post-production.

Horror hit Paranormal Activity actually first debuted on screen in 2007. But it'd be two years before it got a full wide release in cinemas, and by then the ending would have undergone changes (and a planned remake abandoned).

20th Century Fox was having doubts about 1985's Cocoon, meanwhile, to the point where Robert Zemeckis was fired as its director (making Back To The Future instead!). In came Ron Howard though, and changes would get underway...

Stories of both are told in this episode.
