Marvel’s ‘Fantastic Four’ introduces powerful new characters to the MCU, and ends with tease for ‘Avengers: Doomsday’—here’s the ending and post-credits scene, explained.

Galactus is played in Fantastic Four: First Steps by British actor Ralph Ineson. The star has come a long way since playing David Brent's obnoxious friend Chris Finch in The Office (UK), with acclaimed turns in Game of Thrones, Chernobyl and Robert Eggers' The Witch bringing him to Hollywood's attention.
