The 16-year-old actress was astonished to see how matured her co-stars appeared since the first movie in 2010, but insisted that working with the same cast as before was exciting, reported Contactmusic.
"It was so fun. Being able to be Hit-Girl again was a surreal experience, because you often leave a character behind especially at 11-years-old," she said.
"Then four years later to put on the costume again and work with the same actors again, wearing the same wig, being with the same hair and makeup team, it's crazy and totally surreal to do it again," Moretz added.
"It was so much fun. Aaron and Chris, they're like my brothers - and they've changed so much! They've become such men, you know? I worked with them when I feel like they were babies and I was a baby, but now we've grown up so much.
"It's like a little group of adults now, it's funny. I've had such a great time reliving the character and bringing in more dimensions, while taking an older approach to the role. I liked seeing what I could play with in the part," she added.
