He told NME: "Breaking Bad will end as a dream, I like that idea of [Walter] being really clever for ages and he wakes up or he comes out of an MRI scan and he hasn't got cancer, and they live happily ever after."
He added: "He's got all the best intentions, or did have, and its spiralled out of control."
Turner said: "He's got to to have a moment to redeem himself."

Arctic Monkeys' frontman also revealed that he would like to have had the opportunity to work on the show's soundtrack.
"I would love to write music for Breaking Bad," said Turner. "But I think I've run out of time unfortunately as there's only a couple of episodes left."
When asked by Helders what style his score would be, he added: "I'd probably do reverby guitar in E minor."
Arctic Monkeys are currently number one in the UK album chart with AM. Watch their latest video for 'Why'd You Only Call Me When You're High?' below:
