Earlier this year, speculation on the film included rumours that Netflix would be given first-run rights before AMC. Bryan Cranston had confirmed the project, but was unable to say whether he would be involved, given that Walter died at the end of the series. "I don’t know if there’s an appearance – flashbacks, flash forwards," he told radio host Dan Patrick earlier this year. "But I’m excited about it because it’s Breaking Bad and it was the greatest professional period of my life. And I can’t wait to see all those people again, even if I just come by to visit."
It looks like he will be involved in some capacity, however. Some sources suggest that the story will follow Jesse after his escape from the Aryan Brotherhood's HQ (if you'll remember the final episode, he escaped in Jack Welker's car.)
Stay tuned for more info as we have it.
