Bermudian actor Kristen Darrell was caught off guard when a stranger in a London cinema asked her if she was in the upcoming Spider-Man blockbuster after she appeared in the movie’s trailer.

The answer was “yes”, but she had been sworn to secrecy.

Ms Darrell said: “I got a bit flustered and wasn’t sure how to answer because I had signed like three non-disclosure agreements and wasn’t sure if I could say anything.

“I very quickly pulled up the trailer on my phone while still in the theatre and, sure enough, I was in it. I was so excited.

“I think I texted so many people to let them know and then realised I should probably talk to my agent and make sure I could talk about it — she quickly wrote back that it was fine and so I started to tell everyone I knew about it.

She added: “It was all a bit surreal and absolutely hilarious.”

Ms Darrell, who works as an actor in London, got an audition for Spider-Man: Far From Home last year after she finished filming a role in the Amazon Prime series Hanna in Budapest.

She said: “I was literally on the train from the airport when my agent sent me an e-mail asking if I could make it to an audition for an action film the next afternoon.

“I said sure. I had no idea what the film was until I got there. I was pretty excited about it.

“I did the audition, but didn’t hear anything for about a month, so I had put it behind me. As an actor, you get many auditions, but you don’t usually hear anything back unless you actually get the part.”

In July she got a call from her agent to ask if she would be back from holiday before the second week of August because she had landed a role in the Spider-Man film.

Ms Darrell said: “I almost screamed, but I was working somewhere else, so I had to be quiet. But I sure did a dance.

“As a comic book fan, it’s a dream come true.”

Spider-Man: Far From Home, starring Tom Holland, Jake Gyllenhaal and Samuel L. Jackson, and directed by Jon Watts, follows the superhero as he fights supervillains across Europe.

Ms Darrell, who played a New York City police officer, said she had worked with Mr Holland on the shoot and that he was very welcoming.

She said: “Tom was lovely. He made sure to introduce himself to all of us, and would have conversations here and there, but was pretty professional.

“The shoot was pretty cool, the director was really cool and fun and the cast and crew were really easy to get along with. The whole process was amazing from start to finish.

“We had a lot of freedom to make jokes and stuff, the director loved it when we improvised.”

Ms Darrell added the shoot was also “pretty secretive” as the film was shot after the release of Avengers: Infinity War — which concluded with a cliffhanger ending — and before the follow-up, Avengers: Endgame.

She said: “We couldn’t print our lines out and we didn’t get them until we started filming, like at the beginning of the day when we came to set.

“I don’t even think the words ‘Avengers’ or ‘Endgame’ were even spoken on set.”
