Helena Zengel was just 11 years old when she first met Tom Hanks, and she didn't really understand what a big deal he is. The German actress plays opposite the Hollywood megastar in the western News Of The World, set on the Texan frontier in 1870.
She has already landed Golden Globe and Screen Actors Guild award nominations for her role as a girl who speaks no English and who has been living with Native Americans before being taken from them, and is now in the race for an Oscar nomination.
Hanks plays a Civil War veteran who travels from town to town reading out the news and who reluctantly agrees to return the youngster to her distant settler family, travelling hundreds of miles across dangerous terrain.
"If you had said 'Tom Hanks is in another movie', I would have known he's an actor and I knew he was a bigger deal than some other actors, but I didn't quite know that he's a real big deal," Zengel, now 12, admits as she chats on Zoom from her home in Germany.
"So, when I knew I was going to play the role, I knew he's an actor, but then later on I learned he's such a big actor and it was such an honour to work with him. He's just great, he's very nice and I was really impressed by him, he's a gentleman."
Zengel casts her mind back to their first meeting, before the film's shoot in New Mexico.
"At the beginning I was a little bit in awe, not quite as self-confident as I am usually because he's tall, he can be loud, he's American and he's such a big actor.
"But then, later on, we really had fun because he's funny, he's so nice, he is totally not like a superstar you would expect.
"At the beginning I was like, 'Okay, he is obviously older than me, he did so many movies and we are going to be acting partners but it is never going to be like a friendship or anything', but it did, it just happened, and I think it's great to get a relationship with an actor because it makes it so much easier to play with each other."
News Of The World is Zengel's first Hollywood film, after starring roles in German films including System Crasher and Dark Blue Girls.
She first met the movie's director, British filmmaker Paul Greengrass in a London hotel, when she was still working on English.
"In the beginning I was quite confident with the English, I pretty much understood everything he said, I understood what he meant. But then my brain got tired and then I was like, 'What did he just say?'
"So when he actually said I got the role I was totally confused and I was just talking and I think he was wondering if I didn't get it or if I didn't want it, because I wasn't reacting.
"At the end I said 'When are we going to know if I got the role or not?' and he was like. 'If you want to make this movie, you've got the role, I want to work with you!'"
Zengel is great company, naturally ebullient and enthusiastic about everything. But News Of The World forced her to tap into a very different side of herself, her character Johanna barely speaks and her relationship with Hanks' character Captain Kidd is close to wordless.
"In my last movie my character was very loud and self-confident, she speaks a lot but she still has her quiet moments where she has that look in her face where she could start to cry and you can't tell why, it's just her face looking at you.
"I think it was very interesting to see how Johanna and him get closer even when they can't talk with each other. You have to show everything you can with just your eyes, and it's the hardest things you can do when you play a role but I wanted to take a chance and just try and do it."
Much easier for Zengel were the films action scenes, in which the keen rider got to show off her skills in the saddle.
Particularly exciting was the film's centrepiece shoot-out, with a trio of unpleasant men who are trying to buy the young girl from Hanks' character.
"We started very low (in the desert) and then we got higher and higher and higher and later and it was getting slippery.
"We were between the rocks and we had to hike up there and the camera team, the lights, the sounds, all the things you have to get up there, it was very tough, but it was just so fun.
"We found snakes and spiders, it was such a crazy shoot but it was amazing and one of the greatest times of my life and I think I will never forget it, my first Hollywood movie and it was with Tom Hanks."
