Scarlett Johansson will host "Saturday Night Live" on May 2, the weekend "Avengers: Age of Ultron" opens in U.S. theaters. No musical guest has been announced.

It will be her fourth time hosting the NBC show. Her first was in 2006, her most recent in 2010.

The actresses' latest gig follows the March 7 "SNL" appearance by her "Avengers" co-star Chris Hemsworth, who had some fun with his Thor character in a sketch. Given the timing of Johansson's return, another "Age of Ultron" sendup seems unavoidable.
