Tom Holland says the first time he met Willem Dafoe on the set of 'Spider-Man: No Way Home' he had no idea who he bumped into because the actor was wearing a cloak for secrecy

• Willem Dafoe returns as the Green Goblin in "Spider-Man: No Way Home."
• Tom Holland told fans a funny story of the first time the two met on set.

Tom Holland's first time meeting Willem Dafoe on the set of "Spider-Man: No Way Home" probably wasn't exactly what the star had in mind.

During a fan event to debut the film's new trailer, which Insider attended, Holland recounted meeting Dafoe who is reprising his role as the Green Goblin from 2002's "Spider-Man" in the sequel.

"I just sort of bumped into this guy in a cloak and was like, 'Watch out, mate,'" Holland told the crowd at the Regal Theater in Sherman Oaks, California on Tuesday night. "He took his hood off and I almost got really scared. I was like, 'Oh shit. The Goblin's here.'"

Holland said there were no hard feelings though.

"He was lovely. He was really wonderful," he added. "There's a story that I would love to tell, but I just cannot tell it yet. You will hear it one day. It's very exciting."

Dafoe is one of several actors who is reprising his role as an iconic Spidey villain in December's "Spider-Man: No Way Home." The latest trailer confirmed the return of Jamie Foxx as Electro along with the Lizard and the Sandman.

Alfred Molina was previously confirmed to reprise his role as Dr. Otto Octavius in the sequel who becomes Doc Ock.

Their return is a big deal because the five characters have appeared as villains in Tobey Maguire and Andrew Garfield's "Spider-Man" movies, prompting fans to wonder if we'll also see the heroes swing into action once more.

Of the villains, Holland said they all came to set a week before they started shooting to meet director Jon Watts and Holland and "hang out on set and have a good time." But they needed to keep a low profile on set.

"At that time, all of the villains in the film, it was a huge secret that they were in the film," Holland said. "So, they would walk around set with these cloaks on. Naturally, these guys were really excited to be coming back and bringing these roles back to life."

When Holland was asked his favorite villain to go face-to-face with in the entire Marvel Cinematic Universe, the actor said, "I think my favorite has to be Alfred Molina. Working with him on this film was so fun because he was so blown away by the improvement with all the technological advancements that filmmaking has made."

Reminder: Spidey squared off against Thanos in "Avengers: Infinity War" before getting snapped into dust.

Holland also said that working with Dafoe was great as well.

"The first rehearsal I had with him was pretty surreal. It was pretty surreal for reasons I can't really talk about because I want you to experience it in the theater," Holland said.

"Spider-Man: No Way Home" is in theaters on December 17.
