Tom Holland's "safety blanket" is Robert Downey Jr..
The 21-year-old actor feels incredibly lucky to have befriended the 52-year-old star - whose Iron Man makes an appearance in 'Spider-Man: Homecoming' - because not only can he call him for advice, they genuinely enjoy one another's company.
He said: "He is like a safety blanket, Robert.
"He's always available to call up and be like, 'I don't know how to do this - can you help me?' He's always willing to help me out and give me advice and stuff, but the nice thing about Robert is we're friends.
"He's just a nice guy. We can sit down and have dinner and comfortably just relax with each other for a really long time. And I'm so lucky that he was willing to show up and help me out on this little picture."
But one thing Tom didn't need any help or advice with when it came to playing Spider-Man was the action scenes.
He told the Belfast Telegraph: "If I wasn't an actor I'd be a stunt man, and the fact that I have been given the opportunity to do both is really fantastic."
The British actor is still amazed he's landed the role of the web-slinging superhero because it's been an ambition of his since he was a child.
He recalled: "Five years ago I was at the Empire Awards in London and one of the interviewers asked me if I could be a superhero, who would I be.
"I said, 'In 10 years, I'd like to be the Spider-Man after Andrew Garfield'. I would never have guessed that it would have come true so quickly. (I pinch myself) nearly every day.
"When I found out I got the part, I was jumping for joy, screaming and shouting - my poor little dog, Tess, was on my bed and was like, 'What are you doing? Relax.'
"It's a crazy thing to be able to say. I have been in my room as a kid saying 'I am Spider-Man' since I was like five, but now actually being able to say it with some truth behind it is kind of insane."
