The 36-year-old actor said there is a possibility for him to star in the superhero movie, reported Ace Showbiz.
"There are certain things I can't speak on. But I will say, however this works out, it's definitely the fans' fault. I was at home minding my own business and fans start creating these fan-made videos of me as Green Lantern and I looked into it," Gibson said.
"I've been a fan of the Green Lantern. I took the oath, and I had a meeting at Warner Bros. And certain things were said and talked about. We'll just see what happens.
"Green Lantern (2020)" is planned by WB for June 19, 2020. Ryan Reynolds previously played Hal Jordan in the 2001 movie. The actor now suits up for a "Deadpool" movie due to be released by Fox on February 12, 2016.
