There is a new Spider-Man movie coming out in 2018 and it has nothing to do with the recent "Spider-Man: Homecoming" or "Avengers: Infinity War" films from the Marvel Cinematic Universe. Instead, this is a new animated movie -- the second big-budget Marvel theatrical movie following "Big Hero 6." This one is called "Spider-Man: Into the Spider-Verse" and features not just one Spider-Man, but multiple versions of the character from different parallel universes. That also includes Spider-Gwen -- someone who comic book fans know but she is someone new for moviegoers.

Check out the trailer below and then learn more about the movie and characters.

What is the new Spider-Man movie about?

First off, the main thing that fans will notice about the "Into the Spider-Verse" trailer is that the main character is not Peter Parker, but Miles Morales. For those who never watched the cartoons on TV or read the comic books, Miles is from the Ultimate Universe timeline -- which is what a lot of the ideas from the "Avengers" Movies came from as well.

Miles Morales is a young Latino boy who, in the comics, gets his powers after Peter Parker dies in battle. It looks like the movie is going to try something new, as an older version of Peter Parker is here to help Miles learn how to be a hero.

Not only that, but Spider-Gwen -- a character from yet another parallel Earth -- also makes an appearance at the end of the trailer.

Much like the cartoon showed on television, there are different Earths, and each world has its own unique Spider-Man. Peter Parker is from Earth-616 -- the main Marvel Comics timeline. Gwen Stacy is from Earth-65 -- a world where Gwen Stacy is bitten instead of Peter Parker.

Miles Morales is from the Ultimates world -- Earth-1610.

What else do we know about the movie?

There was a comic book line called "Spider-Verse" that went on sale in 2014 and introduced the idea of the multiple versions of the characters. There is no telling how many different versions appear in the new movie, although there were only three in the "Spider-Man: Into the Spider-Verse" trailer.

Phil Lord, who made "The LEGO Movie," wrote the script for and the cast is shaping up nicely. Shameik Moore voices Miles Morales, replacing Donald Glover, who voiced the cartoon character on TV. Hailee Steinfeld, who starred in "True Grit" is Gwen Stacy while Jake Johnson ("New Girl") is Peter Parker.

"Spider-Man: Into the Spider-Verse" comes out on Dec. 14, 2018.
