The 35-year-old 'Guardians of the Galaxy' actor voiced hero Emmet in Phil Lord and Christopher Miller's animated film, reported Metro.
"I don't know anything. I hope I'm back. I loved working with Chris and Phil, and I hope Emmet is crucial to the story. But I can also see a world where they can kind of do anything and call it The Lego Movie 2, do you know what I mean?" he said.
"It could be about a different character, it's not like other cartoons in that way. I hope that Emmet isn't disposable, he was such a great big part of that movie.' I'm so proud of that movie.
The sequel to 'The Lego Movie' has a release date of May 26, 2017.
