The Avengers is a 2012 American superhero film based on the Marvel Comics superhero team of the same name, directed and written by Joss Whedon. The film brings together characters from previous Marvel Cinematic Universe films: Robert Downey Jr. as Iron Man, Chris Evans as Captain America, Chris Hemsworth as Thor, Mark Ruffalo as the Hulk, Scarlett Johansson as Black Widow, and Jeremy Renner as Hawkeye, with Samuel L. Jackson as Nick Fury and Tom Hiddleston as the villain Loki.

The plot follows Fury as he assembles the team to stop Loki from subjugating Earth using the Tesseract, a powerful energy source. The Avengers was a watershed moment in cinema, proving that a shared cinematic universe with multiple standalone franchises converging into a single crossover film could work commercially and critically. It grossed over $1.5 billion worldwide, becoming the third highest-grossing film at the time, and received widespread praise for Whedon's handling of the ensemble cast and the Battle of New York sequence.
