Godzilla first appeared in Ishiro Honda's Godzilla in 1954. The monster went on to star in 27 other movies produced by Japanese film company Toho Co., Ltd., and also inspired a number of video games, novels and comic books.
The plethora of Godzilla material already available may provide inspiration for the new sequel or sequels. Godzilla (2014) features new monsters, M.U.T.O.s, but there are plenty of old favorites, including Mothra and Mechagodzilla, that could play a role in future films.
It is currently unclear if Gareth Edwards will return to direct the sequel.
