A loud-mouthed fan was battered by fellow cinema-goers after blurting out key elements of the plot of one of the most anticipated films of the year.
The man was leaving the three-hour screening of Avengers: Endgame when he revealed several spoilers to crowds waiting to watch the movie in Causeway Bay, Hong Kong.
Endgame is the final installment of the Avengers series and the sequel to last year's Infiinity War.
It follows directly on from the 2018 release which saw villain Thanos wipe out half the world's population, although questions remained as to why he didn't kill all the Avengers.
It is the culmination of 11 years' of films which began in 2008 with Iron Man and is the 22nd release.
