Star Wars leading man John Boyega is among those left without a seat for 'Avengers: Infinity War' in its massive opening weekend. Boyega posted about his experience on Twitter. Fandango reported more than 1,000 Infinity War showings had already sold out ahead of its April 26 preview debut. Black Panther, released in February, was Fandango's best-selling superhero movie pre-sale in the site's history, but the latest Avengers surpassed that number in just six hours.
