Christopher Nolan was developing his spy movie Tenet for decades before its release in 2020. In 2014 Nolan already was fully in the writing process on the script. While the general public didn't know much about the project, other filmmakers, including the French director Luc Besson probably could know something about it. And so trying to beat Nolan at his own game, Besson quickly wrote and directed his own spy movie with a palindrome title: Anna.
