With superhuman speed, The Avengers has flown past the previous world record to take in the fastest $1 billion box office film gross.
The film passed the $1 billion mark 10 days after its release in the US and most other countries.
The Avengers also recently set another Guinness World Record for the biggest US box office opening weekend, when it pulled in $200.3 million (£124.2 million) in ticket sales.
The superhero film is produced by Marvel Studios and distributed by Walt Disney Pictures.
Robert Downey Jr, Chris Evans, Chris Hemsworth, Scarlett Johansson, Mark Ruffalo, Jeremy Renner, and Samuel L Jackson all star in the Joss Whedon-directed production.
The previous record holder, The Lord of the Rings: The Return of the King, passed the $1 billion mark at the international box office after nine weeks and four days following its release in December 2003.
