The Nun begins its reign of terror this weekend and here's where it fits in with the other movies in 'The Conjuring Universe.'

'The Conjuring' proved to be a highly - successful film that led to a spin - off, 'Annabelle,' then 'The Conjuring 2' and Annabelle's sequel, 'Annabelle Creation.' This week sees the release of the next chapter, 'The Nun.' You don't have to see all of the other movies before watching 'The Nun' (though you really should) thanks to this full timeline of events in 'The Conjuring Universe' so far.
