Natalie Portman

Gal Gadot, Natalie Portman and Amy Adams in star-studded Imagine cover

Gadot enlisted fellow superheroes Natalie Portman (Thor) and Mark Ruffalo (Hulk) for the cover, with more than 20 others each singing a line of the song.

Will Ferrell, Amy Adams, Kristen Wiig, Sia and Cara Delevingne also took part.

The star said she had chosen the song for its "powerful and pure" message of unity during the coronavirus pandemic.

She had been inspired by a clip of an Italian man playing the song on his trumpet on his balcony to his neighbours who were self-isolating.
