Almost 20 years later and the 1997 film is still in the top. Titanic was number one for all these years until 2009 when ‘Avatar’ came out, taking the #1 spot. But unbelievably impressive after 20 years, they are still in the top 2 with $2B made worldwide.

Check out the list below and even some 2016 moveis have made the top 50.
