The latest film in the Spider-Man franchise starring Tom Holland has already grossed more than $1 billion worldwide.
The movie came out in mid December, but many fans are still yet to see it.
In a bid to stop any spoilers from being released, cinema chain Odeon has reportedly put up signs warning viewers not to discuss the film’s dramatic twists after leaving the cinema.
“It sounds extreme but there have been a few instances where people have queued for a long time to get in to see the movie, only to have people reveal the ending as they leave.
“That’s often caused tension and the last thing cinema bosses want is arguments and potential scuffles breaking out,” a source told The Sun.
The outlet also said that cinema staff have now put up a sign which reads: “Spoiler alert! please refrain from talking about the film you have just watched until you have left the building to prevent spoiling other guests’ experience. Thank you.”
The Mirror has contacted the Odeon for comment.
Some fans of the Marvel superhero have accused viewers of intentionally giving away the film’s ending while standing in the cinema foyer.
One took to Twitter writing: “@ODEONCinemas A film as highly anticipated as Spiderman and we had people running down the corridor, entering the screen and shouting potential spoilers.
“For a showing where people have waited a long time trying to avoid spoilers only for that to be allowed.”
As well as Tom’s Spider-Man, the third film of the MCU franchise sees Zendaya’s Michelle MJ Jones-Watson make a welcome return.
Tom and the actress have fallen for each other since meeting on the set of the film, however they were reportedly warned that they shouldn’t get romantically involved.
Producer of the Marvel movies, Amy Pascal, says she told the couple, both 25, that it would be better to keep their relationship professional before they went public with their romance.
She told The New York Times : “I took Tom and Zendaya aside, separately, when we first cast them and gave them a lecture.
“Don’t go there — just don’t. Try not to.”
However it doesn’t look like the picture-perfect pair took Amy’s advice as they reportedly fell for each other behind the scenes.
Tom and Zendaya’s relationship is still in its early days, but they seem to be head over heels for each other.
They were first spotted kissing in Los Angeles in July and made their stunning red carpet debut for the new film in which Zendaya stunned wearing a barely-there dress with web detail.
