Scarlett Johansson has revealed that her twin brother Hunter was her most enthusiastic supporter at the premiere of Jurassic World Rebirth

In an interview with E! News, Scarlett said: "He was the loudest audience member. I knew that that would be the case because he loves Jurassic so much and was like, there for it."

She added: "He would've been there either way because he's a fan and the movie is so explosive. He was literally orchestrating the John Williams music and was just like, so loud."

Scarlett admits that her watching the film with her twin brother was particularly special as they had both loved the original 1993 flick Jurassic Park together as children.

The Jojo Rabbit star said: "That was really fun because we saw the movie together when we were nine or 10 in the theatre, and here we are in this full circle moment. It's kind of crazy."

Johansson realised a childhood dream by starring in the movie and has vivid memories of her first day on the set of the film.

She recalled: "Even our first day at work, we landed in Krabi, Thailand, took a car to a boat to another car to another boat to this remote island we were shooting on.

"By the time we got down to this little jungle path to the beach, you're like, 'Oh my god, it's really Jurassic Park out here!' It's just so embedded in my memory."

Scarlett's co-star Jonathan Bailey was also pleased to have the support of his scientist sister as he takes on the role of Dr. Henry Loomis movie.

The 37-year-old star explained: "At the London premiere, my sister is a genetic counsellor for the NHS.

"And my character says, 'Science is for all of us', and I could just see she gulped and she was like, crying."

Jonathan continued: "You remember how important this film is in all of its different messages as well as the thrills and the highs. There's a real heart to the Jurassic films."
