On why he did the movie, Idris Elba stated: "I come from an era where these sort of films were the norm, like high-anxiety, 'Run, chase, run, chase, look out, look behind you!' This was an opportunity for me to make a film like that. I've done thrillers before, but this was the first time it involved this cat-and-mouse aspect to it. I was really intrigued by the family dynamic, the daughters, the nature of grief, this doctor who's essentially someone that's composed and tries not to panic, found himself doing just that," Elba tells Complex about the survival thriller directed by Baltasar Kormákur. "I just love the script. I love Baltasar, the director. I wanted to work with him. He's made some really incredible survivor movies, and I just wanted to get his take on what this might be like."

When Dr. Nate Samuels (Idris Elba) is in the lake looking for keys, he's wading almost shoulder-deep in the water. In the next shot when he is out of the water, his shirt is completely dry.

After credits, we hear the sounds of the Savannah and lions roaring. When the title comes up, several slash marks appear on it, followed by a lion growling.
