Karen Gillan has been praised for shaving her head for Guardians of the Galaxy.
Marvel Studios boss Kevin Feige thinks it's ''really cool'' that the 26-year-old actress was willing to show such commitment to her part as Nebula in the new intergalactic superhero movie.
Speaking to BANG Showbiz, Feige said: ''She was willing to shave her head and she not only ended up shaving her head, but at Comic Con last year she came out on the panel in a wig and dramatically revealed it - it was so ballsy and it was so awesome. And she did all of her behind-the-scenes interviews completely bald and she is beautiful with hair and without hair, so it was really, really cool that she was willing to do that.''
When asked about her performance in the movie, he added: ''Her audition was good and Nebula, the character she is playing, is a conflicted character and needs to have a number of different layers and a performance that comes through.''
