Bryan Cranston will reprise his role as Walter White.

The 58-year-old actor - famed for his portrayal of the crystal meth producer in the AMC drama Breaking Bad - will "definitely" return in the new spin-off Better Call Saul, despite his character being seemingly killed off in the show's finale last year.

"With the new show coming and the possibility of flashbacks or flash-forwards, there is going to be something with Walter White. They won't do it as a gimmick, it will actually mean something when they do it. Definitely expect the return of Walter White in some way, shape or form in the new show," a source said.

However the insider was unable to confirm whether Bryan Cranston's Walter White - for which he won a Best Actor Golden Globe - will be alive when he returns to the small-screen. "I wouldn't be able to answer that, but I know that they have options of bringing him back and that they will do it in an awesome way," the insider said.

Although full cast details for the new show are yet to be released, Bryan recently hinted at the return of his character while he was quizzed about the end of the show. "You never saw a bag zip up or anything. I don't know. Never say never," he told CNN.
