The couple were among the stars who attended a screening of The Avengers: Age of Ultron on Monday evening (13 April).
Chris reprises his role as Thor in the Marvel superhero sequel to 2012's The Avengers. He's also played the character in Thor and Thor: The Dark World.
Other stars of the movie include Scarlett Johnasson, Chris Evans, Robert Downey Jr. and Samuel L. Jackson.
Chris and Elsa made a picture perfect couple at last night's Los Angeles premiere, with Elsa dazzling in a very Marilyn Monroe-esque white halterneck dress.
The couple are parents to three children: daughter India, two, and twins Sasha and Tristan, one.
