What is the highest grossing action movie ever?

I am an upcoming writer who is developing a T.V. show called Spoof Central where other movies are hysterically made fun of to send to a T.V. channel. So far I've written scripts for 113 hour long spoofs to show my dedication. Some scripts are downright funny like The Texas Leafblower Macre and some are just desperate like Bambo, a spoof of Rambo. To keep from having more Bambos than hits, I want you to come up with the title of the highest grossing action movie ever because... 1. Highest grossing means the amount of money the movie makes and that depends on the amount of people that see it. People laugh at things they know about, so.. yeah. 2. The only action movies I've made fun of are ones I don't have the best hopes for. So can you please get the title?
