The AMC series is due to start its fifth and final season next month, but the 56-year-old star revealed that the show could continue on the big screen.
"It's not far-fetched," Cranston told the Los Angeles Times of a Breaking Bad movie.
"I wouldn't mind visiting that possibility," he continued. "And this is coming from a guy who doesn't know anything of how the show's going to end.
"If it doesn't end up in a total apocalypse, who knows?" Cranston added. "Maybe we could revisit Walter White a year down the road and see where his life has gone. If he's still alive, that is."
Cranston will host the Television Critics Association Awards next month.
Breaking Bad star Giancarlo Esposito recently confirmed that the fifth season will pick up right where the show left off.
