Avengers: Infinity War appears to be rewriting the history books with a $630m (£457m) global opening weekend take, according to industry tracker Exhibitor Relations.
If confirmed, the superhero sequel would overtake The Fate of the Furious’s $542m global opening weekend haul, a record set in 2017.
The film is also seen taking the all-time domestic opening record, making $250m in the US alone.
Official figures will come out on Monday, but this would put Avengers ahead of Star Wars: The Force Awakens’ $248m take.
