The three-time Academy Award nominee, who plays the mysterious Man in Black, spilled the beans during an appearance on BBC Radio 4, reported Ace Showbiz.
"Yeah, you know, as a matter of fact, I was just talking to Jonah Nolan last night, who's a creator of this thing with his wife Lisa Joy, and yeah, they're doing another season," said the 65-year-old actor.
"They're going to do ten more episodes, and I will be involved."
The sci-fi western series will return for its second season in late 2017 or the first half of 2018 due to its elaborate production.
