A movie based on video game maker Naughty Dog’s hit Uncharted series is still in the works, but hasn’t had much luck with the tricky task of finding the perfect star to play primary protagonist Nathan Drake or figuring out how to get the script exactly where it needs to be.

According to reports, Guardians of the Galaxy and Jurassic World star Chris Pratt is the most recent to be offered the role of Drake, but the actor has declined that offer. It’s also being reported that yet another writer has been brought in to work on the screenplay, Oscar winner Mark Boal (The Hurt Locker, Zero Dark Thirty).
