With Obamas involved in the movie, plus its perplexing themes, fans couldn't help but theorize that there's a deeper message behind Roberts' new movie!

One fan wrote, "The movie 'Leave the World Behind' is definitely a message to what's happening and what's to come. It's very much in line with what we've been saying for years: Stock up on none perishables and water. Also, the fact that the Obamas are exec prod'ers is making my dog ears go up."

Former ESPN host Jemele Hill shared, "I'm watching Leave The World Behind and the Obamas being executive producers of this is exquisite, masterful trolling. There's also some much larger discussable points to it. But conspiracy theorists are gonna pass out watching this."
