Charlie Cox says that 'best friend' Tom Hiddleston was one of the first people he told about his 'Spider-Man: No Way Home' cameo

• Charlie Cox said that he confided in Tom Hiddleston about his return in "Spider-Man: No Way Home."
• Cox, who had a cameo as Matt Murdock/Daredevil, said that Hiddleston was one of his "first calls."

Charlie Cox stayed tight-lipped about his surprise cameo as Matt Murdock/Daredevil in "Spider-Man: No Way Home" before the movie's release, but he did tell fellow Marvel star Tom Hiddleston.

"One of my first phone calls, and I knew I could tell him because I also knew he knew, was Tom Hiddleston, he's one of my best friends," Cox told ComicBook.com.

Cox said that at the time, Hiddleston was filming "Loki," a Marvel/Disney+ series in which he stars as the titular God of Mischief.

Cox also said that Hiddleston, who costarred in the Broadway show "Betrayal" in 2019, was already aware of his return as Daredevil.

"He said to me, 'Whatever you do, when the film comes out, you've got to sneak into the back of a theater, because it will go crazy,'" Cox recalled. "And I remember thinking, 'No it won't.' It'll be nice to be there, but I think he's thinking what it would be like for Loki to appear in that moment, where the Loki fan base is unlike anything I've ever seen in my life."

Cox previously played Matt Murdock/Daredevil on Netflix's Marvel series "Daredevil," which lasted for three seasons between 2015 and 2018. Following its cancellation, fans rallied for the streamer to revive the show, to no avail.

He appeared within the first few minutes of "Spider-Man: No Way Home," Tom Holland's third standalone film about Peter Parker/Spider-Ma, which hit theaters in December.

At the start of the film, Peter struggled with what to do now that the world knows of his superhero identity.

Cox's lawyer character appeared in Peter's apartment in a scene with the teen web-slinger, Aunt May (Marisa Tomei), and Happy Hogan (Jon Favreau).

Matt gave them legal advice and briefly showed off his superhuman reflexes by effortlessly catching a cement brick that was hurled through the window behind him. He cheekily chalked up his skills to being "a really good lawyer."

The moment was praised by fans, but Cox recently told RadioTimes.com that when he went to a showing of the film to witness the audience's reaction, it was "dead fucking quiet!"

Cox and fellow "No Way Home" star Andrew Garfield, who returned as Peter Parker/Spider-Man, also met up in Atlanta during production and spent an entire lunch date facing a wall so they wouldn't be spotted together and raise suspicions.
