Trivia: Near the end of the film, as Dani is lifted and being carried to the dinner table, if you look closely, you can see the ghostly image of her deceased sister's face (with the exhaust hose in her mouth) in the background. It's been superimposed over the trees in the distance. It's very subtle and easy to miss, but if you know where to look, it's there.
Trivia: During one epic car crash near the start, just after the shooter gets taken out by the digger, if you know what to look for you can see Ryan Reynolds in the background, filming a post/advert for social media. Not a mistake, because it's just a tiny figure at the back of shot, but pairing the film and the post together it's fun to look for. (00:14:42)
