Bird Box Barcelona is the long-awaited revisitation of the world established in 2018’s Bird Box. Not necessarily a direct Bird Box sequel, Bird Box Barcelona leaves behind the locations and characters of the first film to explore what was, before the arrival of the franchise’s society-destroying creatures, one of Spain’s most popular tourist destinations. The film stars Mario Casas, Diego Calva, Georgina Campbell, and more, and it is especially different from the first Bird Box in that its primary language is Spanish (for those looking to enjoy each actor’s original performance, be sure to switch languages on Netflix).
