A Marvel fan in the US is doing his part to help Avengers: Endgame become the highest-grossing movie in history: He's seen the superhero blockbuster a whopping 110 times.

"I work 10 hours, watch end game 2 times on weekdays at least 6 hours," said Agustin Alanis in a message on Twitter on Monday that was accompanied by a picture of himself and a theater attendant holding his 110th ticket stub.

Alanis' feat beats another record set last year by Anthony Mitchell, who saw Avengers: Infinity War 103 times, which got him a place in the Guinness Book of World Records and a trip to the Endgame set.

Alanis has been chronicling his trips to see the movie on Twitter, posting a picture of himself at each viewing with his ticket stub.

The latest mega-blockbuster has earned a worldwide total of $2.73 billion so far, putting it within range of beating Avatar, which raked in $2.79 billion to become the highest-grossing movie of all time.
