Chloe Moretz loved bringing maturity into her reprised role in 'kick-Ass 2'.

The 16-year-old actress admits that it was bizarre seeing her character Hit-Girl grow into a mature young woman since the first film in 2010, but she insists she was able to experiment with her alter-ego more easily because she was working with the same cast as before.

Speaking to Flicks and Bits, she said: ''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.

''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.''

The brunette beauty admits that she is so close to her co-stars Aaron Taylor-Johnson and Chris Mintz-Plasse that they've become like her siblings and she can't get over how much they've grown up.

She explained: ''It was so much fun. Aaron [Taylor-Johnson] and Chris [Mintz-Plasse], 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.''
