"I've got no objection to someone else doing that, but I'm not interested in the idea of a sequel," he told IndieWire"I feel like we made this movie and this is the movie that we made."

Garland, who received an Academy Award nomination for Annihilation's screenplay, made his directorial debut with Ex Machina. The author of the 1996 novel The Beach, he also penned the screenplays of 28 Days Later, Sunshine, Never Let Me Go and Dredd. Although he was an executive producer of 28 Weeks Later, he didn't write or direct that sequel.

"When the thing is done, I'm done with it," Garland said. "I instantly start moving on, so I don't even have an opinion on an Annihilation sequel."

For now, we'll just have to settle for debating about Annihilation's ending.
