Fans saw Cranston’s chemistry teacher-turned drug kingpin Walter White collapse after being shot in the final moments of the series.
But when asked whether he was indeed dead, Cranston told CNN, “I don’t know.
“You never saw bags zip up or anything, or anybody say… you know.”
Ever since it ended, the show has been racking up awards – most recently picking up best international show at the Bafta TV awards – and Cranston says he will always be grateful for the “career-changing” role.
“For some reason it came into my lap and I jumped on it. I knew when I read it, whoever was fortunate enough to get this role, it’s going to change their career – at the time I didn’t know it was going to be me. But I’m very grateful.”
So could there be more? Perhaps even a big-screen Breaking Bad?
