Aaron Johnson thinks his outfit in 'Kick-Ass' makes him look like a "gummy bear".

The British actor - who came to fame playing John Lennon in biopic 'Nowhere Boy' - admits people have commented about the green outfit, but claims it is all in good humour.

He said: "The more ridiculous I looked, the better.

"I always think I looked like a green gummy bear... a 'green condom' is what I get called quite a bit. It was a good laugh.

"I enjoyed the idea of this kid being unique and original and he thinks he's really cool."

The 19-year-old star also reveals he is keen to make a sequel to the critically-acclaimed movie, and thinks his 13-year-old co-star Chloe Moretz's character Hit Girl should teach his character Kick-Ass how to fight.

He told MTV.com: "You can't make him some crazy superhero who's going to be strong. Maybe Hit Girl can help Kick-Ass train because he definitely needs to know how to fight."

'Kick-Ass' is released in the US on April 16.
