Jodie Comer's international cinematic debut.

Ryan Reynolds & Taika Waititi previously co-starred together in Green Lantern (2011).

Filmed in Boston, MA from May 2019-July 2019.

This is the second time Ryan Reynolds has played a character named Guy. The first time was in the animated film "The Croods".

Joe Keery previously worked with director Shawn Levy on Stranger Things (2016)

The movie is set in a fictional, intra-video-game locale called Free City. Its teaser trailer opens with an establishing shot of what is visibly Pittsburgh, however, and its remainder appears to have been filmed in the Boston area. Local landmarks such as Faneuil Hall and the 75 State Street complex are clearly visible.
