The supersized superhero hit Avengers: Infinity War has crossed $2 billion in worldwide ticket sales, becoming only the fourth film to reach that rarefied box-office milestone.

The Walt Disney Co. announced Tuesday that Infinity War reached the mark Monday, about seven weeks after opening. The only other movies in the $2 billion club are Avatar, Titanic and Star Wars: The Force Awakens.

Infinity War currently ranks as the fifth highest-grossing film in the US and Canada with $656.1 million thus far. Its $257.7 million domestic opening weekend set a new record.

The Marvel release has done just as well overseas. In China, the film’s $369.7 million gross to date ranks third all-time. An Avengers sequel to Infinity War is scheduled to be released in May of next year.
