Meng'er Zhang accidentally punched Simu Liu in the face during their first fight scene together.

The Shang-Chi and the Legend of the Ten Rings star— who made her acting debut as Simu Liu's estranged sister Xialing in the Marvel Studios blockbuster — admitted she was "nervous" and went a bit too far after some encouragement from her co-star.

The theatre actress told Collider: "My favourite memory on set was my first fight scene with Simu and I did punch him in the face — and yes, audiences can see it in the film!

"I was nervous because that was the very first fight scene and Simu encouraged me. He said, 'It's okay, it's okay, just go for it, you can't hurt me!'

"So I went for it, I just got into my character. It was an accident but, to be honest... it felt good. [laughs]"

Zhang described working on the movie as a "dream come true" when it comes to her first mainstream project.

She added: "I didn't have any camera experience before, so I didn't know what it was like.

"The whole journey was just like... a masterclass to me. Because I got to work with so many legends, you know?

"It's like a dream come true... I just learned so much from them."

Meanwhile, the actress didn't actually know she was auditioning for a Marvel movie until she was flown out for a screen test with Liu.

She said: "That's when I found out I was auditioning for Shang-Chi. After five days of that screen-test, I got a message from my lawyer.

"I didn't read through, I just scrolled down to the very bottom and I saw, 'Welcome to the Marvel Universe'! I can keep big secrets. I didn't tell my parents — believe it or not, I didn't tell them!

"I kept the secret, you know? And when I had to fly to shoot the film, I had to tell them and they couldn't believe me.

"I said, 'Okay, it's a film, it's a Marvel film'. And my mum was like, 'No, you're lying'. 'No I'm not!' They're really excited!" 

Shang-Chi and the Legend of the Ten Rings grossed an estimated US$94.4 million (S$127 mil) in its opening four-day weekend (Sept 3-5) in the US, setting a new record for the Labour Day openings. 

Overseas, the movie, which also stars Tony Leung and Michelle Yeoh, earned US$56.2 million for a global haul of US$150.6 million. In Singapore, the movie opened on Sept 1 and claimed the No.1 spot with a S$1.9 million gross over the weekend.  — BANG SHOWBIZ
