05. Titanic (1997)
Gross: $2,257,844,554
The only non-franchised or existing IP films to grace the list of top-grossing films of all time, unless you count the actual Titanic as IP. For a long time, James Cameron’s swooning romance at the heart of an oceanic tragedy was the table’s undisputed champ. Introducing an entire generation to a young Leonardo DiCaprio should really earn you all the money in the world, but hey, more than $2.2b isn’t far off. To this day, Titanic isn’t just the only non-IP film in the top 10 highest-grossing movies of all time, but the top 40! The next one is Zootopia at 48.
