Marvel and Sony Pictures dropped the official trailer of "Spider-Man: No Way Home" on Monday, a day after it was leaked on social media.

"Spider-Man" movie's official Twitter handle shared the trailer and captioned it, "What just happened? Watch the official teaser trailer for #SpiderManNoWayHome, exclusively in movie theaters December 17."

The official 3-minute trailer shows Peter Parker's (played by Tom Holland) new difficult life after faux-superhero Mysterio (portrayed by Jake Gyllenhaal) revealed Parker's true identity at the end of "Spider-Man: Far From Home," which was released in 2019.

In the trailer, Parker connects with Dr. Strange (portrayed by Benedict Cumberbatch) in order to make the entire world forget that Spider-Man and Parker are one person. 

However, Dr. Strange cautions Spider-Man: "The multiverse is a concept about which we know frighteningly little." The trailer revealed the return of Dr. Otto Octavius, who is also known as Doctor Octopus. The character was first featured in 2004's "Spider-Man 2." 

Fans were excited to see the trailer, as one of them said they were waiting for Tobey Maguire to return in the upcoming installment of Spider-Man.

"Just waiting for this man to be in the official trailer then my life would be complete," the user wrote.

Another fan noted, "So is the MCU now really going to explain that the multi-verse was caused when Doctor Strange messed up when making an alt timeline where people don't know Spider-Man's identity, rather than Sylvie stabbing Kang? If so there's a lack of communication and cohesion in the planning."

A fan shared screenshots of the trailer and wrote, "Electro, Doc Ock and Goblin that's insane. Anyone who came up behind Peter in the last pic though?"

Another user said the reason why the trailer was not released officially first was that "there is a lot of spoilers in here Loudly crying face cause that's not Dr Strange. that's evil dr strange we are going to meet in 'What If?.' maybe he took over?"

On Sunday, fans went crazy after the leaked trailer of the superhero movie surfaced on Twitter. 

"Spider-Man: No Way Home" is slated to release in theaters on Dec. 17. It will be the fourth movie in the Marvel Cinematic Universe: Phase Four.
