'Avengers' helmer Joss Whedon has quit Twitter following criticism of his latest film 'Age of Ultron'.
Many fans criticised how the 'Avengers' film depicted Black Widow played by Scarlett Johansson, the BBC reported.
Comic-book fans had also criticised Marvel's 'Avengers' superhero film's plot, on the social network.
Many called Whedon sexist and misogynistic and said he had done a "hatchet job" on the character of Black Widow.
Prior to directing the two 'Avengers' films, Whedon was best known for writing and directing the 'Buffy: The Vampire Slayer' TV series.
