David Pastor reveals whether a Sandra Bullock cameo was considered for Bird Box Barcelona. The spinoff, co-written and co-directed by Pastor, was released on July 14 and broadened the scope of Netflix's 2018 hit, Bird Box, by tracking survivors in other parts of the world. It follows Sebastián (Mario Casas) and his daughter Anna (Alejandra Howard), who seek refuge from the same hostile entity that, when viewed, prompts individuals to take their own lives.
