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.

Years before Ryan Reynolds became Deadpool, he starred in a little superhero movie called Green Lantern. Instead of being Reynolds' breakout hit, the movie is one of the better-known flops of the genre.

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.
