NEW YORK — “Star Wars” and the Marvel comic-book movies will join Disney’s upcoming streaming service , potentially giving it broader appeal beyond families with young children.

The Disney service will be the only place to stream those movies on demand in the U.S. as part of a monthly subscription. (So, not on Netflix.)

A price hasn’t been announced yet. The service is expected in late 2019 after Disney’s current deal with Netflix expires.

Previously Disney announced the inclusion of just Disney and Pixar movies and Disney TV shows. Adding the “Star Wars” and Marvel movies could make the new service appealing to teenagers and adults. The Marvel movies include the “Avengers” and “Guardians of the Galaxy” franchises.

The service will also have original Disney movies, TV series and shorts. Disney CEO Bob Iger said thousands of TV episodes and hundreds of movies will be available, though shows from Disney’s ABC network aren’t coming to the service.

Disney said last month that it was considering moving “Star Wars” and Marvel to the new service, but a decision wasn’t announced until Thursday.
