English soccer fans are used to seeing heroes emerge in the historic FA Cup, but may not often witness the sport cross over with the world of Superman and Batman as it did on Sunday in Tottenham Hotspur's third-round clash with Middlesbrough.
Supporters at the match at Middlesbrough's Riverside stadium, along with millions watching across the world, would have seen digital billboards around the ground light up with the words '#ReleaseTheSnyderCut' in designated minutes during play.
The slogan is part of a campaign to pressure Warner Bros to release director Zack Snyder's cut of the movie "Justice League," which features major characters from the DC comic book universe such as Superman, Batman, The Flash and Wonder Woman.
Snyder left the 2017 project in post-production and was replaced by Joss Whedon, who made considerable changes to the film which was released in November that year to mixed reviews.
Warner Bros said last November there were no immediate plans to release an alternative version of the film, which was preceded by "Man of Steel" and "Batman v Superman", also directed by Snyder.
However, campaigners have continued their efforts, and were able to crowdfund the money required to buy four minutes of advertising on the LED boards, with thousands tuning in around the world.
