Rebecca Ferguson finds it "harrowing and weird" when she's not recognised.

The 42-year-old actress has appeared in both the Mission: Impossible and Dune film series as well as The Greatest Showman, but she is convinced she's not as famous as many of her co-stars and she finds it disconcerting when she's not treated in the same way.

She told Harper's Bazaar magazine: "I think a lot of people wouldn't verbalise it, because not being recognised and yet working is one of the most incredible things - but it's also quite harrowing and weird, because there is an ego-boost to being recognised.

"Sometimes I have moments where I go, 'Why do I not have paparazzi? Why am I not having to be smuggled out the back exit?'

"The older I get, the more I think, 'God, I'm grateful.' But then you have to deal with walking down a red carpet and it goes silent because you're not Timothee [Chalamet] or Zendaya."

Rebecca revealed she also has a complicated relationship with social media, adding: "I started my [Instagram] account five years ago, but it always felt wrong for me.

"I've been playing with it, posting private images, hating when I did, but loving the recognition, then hating that I'm loving the recognition - that constant, bloody juxtaposition ... "

The actress also admitted she doesn't feel particularly comfortable at movie premieres or awards shows as she's "not good" at socialising with other celebrities.

She explained: "I don't know who I am in those environments. I'm not good at sitting and socialising with other celebrities, scurrying on the surface of conversation. I get anxious."

It comes after Rebecca declared she can now be more fussy about the roles she signs up for and wants to make sure she can "have a good time on set".

She told The Independent: "I'm at a point now where I can choose to not work with d********.

"I like to have a good time on set, and I like it when people treat the team well. I have no interest in someone walking over people, or sitting with signs going 'Don't talk to me', or whatever silly nonsense.

"Everyone has a technique, and I respect people's technique. Some people are introverts, and some people don't want to interact. That's fine - you don't have to. But let's not be idiots about it."

Rebecca added that she think the lead actor ought to set the tone on a film set but she acknowledged that this approach can also backfire.

She said: "If everyone keeps treating the No 1 as a bloody king or a princess, you're already putting them on a pedestal, rather than seeing all of this as a creative collaboration ... F***! God, I get so annoyed by it."
