Bryan Cranston, who played White, confirmed a Breaking Bad film was coming in an interview last year.
"I don't know if there's an appearance — flashbacks, flash forwards — 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," Cranston told The Dan Patrick Show.
A fifth season of spin-off show, Better Call Saul, focusing on White's dodgy lawyer Saul Goodman, is set to air this year.
Breaking Bad isn't the only TV show due its own movie this year, with Deadwood and The Sopranos both set to air feature-length films this year.
