Green Lantern was a major learning experience for Ryan Reynolds.

At the TIME100 Summit in New York City on Wednesday, April 23, Ryan Reynolds dished on important lessons in moviemaking he took away from his leading role in 2011's 'Green Lantern,' which was a box office failure.

The 'Deadpool & Wolverine' star was a speaker at this year's Time 100 Summit, where he looked back on his career and spoke about his production company Maximum Effort.
