The release date for Star Wars Episode IX has just been announced and it will be on May 24 2019! The movie is directed by Colin Trevorrow.
The Last Jedi is the last Star Wars movie to be released in December as next year, Han Solo will start reclaiming the May release date. Star Wars belongs there! Before The Force Awakens, Star Wars movies were released in May so ending the third trilogy on this date is a great choice and quite symbolic.
