Disney's live-action adaptation 'Lilo & Stitch' has become the first U.S. film of the year to gross $1 billion in worldwide box office revenue.

It was safe to assume that the live-action Lilo & Stitch film would be a modest little earner in theaters, but now it has officially become a billion-dollar monster movie and the first in Hollywood to cross the monumental landmark this year.

Though Disney+ has yet to confirm when the movie will make its debut, it could be coming soon, based on the streaming releases of past Disney movies. Based on the timeframe surrounding past Disney streaming releases, like that of "Moana 2 ," and "Mufasa: The Lion King ," "Lilo & Stitch" could come to Disney+ in late August or early September.
