Samara Weaving wrote Kathryn Newton's texts to help her get a date.

The 34-year-old actress - who is expecting her first child with fiance Jimmy Warden - quickly forged a sisterly relationship with her Ready or Not 2: Hear I Come co-star after they were introduced by directors Matt Bettinelli-Olpin and Tyler Gillett, and Samara took giving out dating advice a step further by taking over communications between Kathryn and her potential suitors.

Discussing her and Kathryn's on-screen chemistry with their co-star Sarah Michelle Gellar for Interview magazine, Samara said: "Well, that was Tyler and Matt playing Cupid. They had her in mind the whole time.

"So they invited Kathryn to a screening of Ready Or Not, and they were like, 'Guys, meet.'

"We'd met briefly at something a million years ago, and she was just as weird and as awkward as me, and we very quickly fell into this sisterly relationship where she's asking me for advice with boys and..."

Sarah clarified: "Oh, she wasn't asking you for advice. You were basically ghostwriting all of her texts."

Samara laughed: "Yeah, I was. And then I would be texting boys about Harry Potter, and then I'd go, 'Kathryn, do you know what I'm talking about?' She's like, 'I've never watched Harry Potter in my life.' 'Well, you're going to go on this date and not know what I'm talking about.' "

Sarah thinks people get a "pleasant surprise" when they meet Samara because she is a "weird gamer nerd" and not at all how they might expect.

She said: "I think people would be surprised because before I met you, I thought of you as this ridiculously stunning Australian bombshell.

"I was like, 'I wonder what she's going to be like?'

"It's such a pleasant surprise when people meet you, because you're not who people think you're going to be. You're even better. You're this weird gamer nerd. We would try to get you to go out and you'd be like, 'I've got a raid tonight.' "

Samara loves to relax with video games and thinks it is helpful

Yeah, I think I'm quite an introvert. The nature of this job and the culture that we are in, we're sort of a slave to extrovertism, so I want to make sure that when I'm at work, I'm of service to everyone. If I'm in a grumpy mood, I know that it has a trickle-down effect.
