Alex Hirsch, creator of the Disney XD series “Gravity Falls,” has been added as a story contributor to Sony’s “Spider-Man” animated feature, an individual with knowledge of the project told TheWrap.

The new film is set to feature Miles Morales as webslinger instead of Peter Parker, marking the big-screen introduction of Marvel Comics’ black and Puerto Rican Spider-Man.

The Miles Morales announcement was made by Sony Pictures Animation president Kristine Belson at a slate presentation last month at the Culver City, California studio.

Miles Morales was created by writer Brian Michael Bendis and artist Sara Pichelli, with Bendis and Marvel editor-in-chief Axel Alonso drawing inspiration from both U.S. President Barack Obama and American actor Donald Glover.

The new Spider-Man movie, which is still untitled, is scheduled to hit theaters on Dec. 21, 2018.
