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.

Ryan Reynolds spoke about his big takeaways from the critically-panned 2011 superhero film "Green Lantern" during a discussion at the Time100 Summit.

Green Lantern, the DC superhero film that further catapulted actor Ryan Reynolds into the limelight, may be considered a box office disappointment, but the experience taught Reynolds the most important lesson of his entrepreneurial career.
