During Marvel Studios’ panel at this year’s San Diego Comic-Con, Kevin Feige unveiled some big surprises for the fans in attendance. After he shared footage from ‘Thor: The Dark World’ (as introduced by the God of Thunder’s mischievous brother, Loki) and ‘Captain America: The Winter Soldier’, the studio head brought out director James Gunn and his cast from ‘Guardians of the Galaxy’ to confirm their roles and to speak a little bit about the only non-sequel in Phase Two. And while Hall H was shocked to discover that footage was available after only 13 or 14 days of shooting, they were far more surprised to see Karen Gillan’s new look for the movie.

During the panel, moderator Chris Hardwick mentioned that Nebula, the granddaughter of Thanos, was famously bald. Then, the former ‘Doctor Who’ companion confirmed this fact and then took off her red wig to reveal her newly-bald head! Fans were definitely shocked by the actress losing her trademark red locks, but it appears that some were more peeved than others. So much so, in fact, that Gunn began to get hate mail about it.

Well, the director has recently fired back at the haters with this tweet from his personal Twitter account:

Personally, I don’t see why it’s even necessary to hate on Gunn. As a fan of Karen’s, I’m going to support everything that she does. Chances are that she was looking to distance herself from her role in ‘Doctor Who’, so what better way to do that than by taking away one thing that she was very known for during her run on that show? Plus, she looks as gorgeous as ever!

Hopefully these rapid fans will lay off of everyone for this temporary change that the actress definitely knew about when she signed on for the role. Anyway, hair grows back. Just like Whovians went wild when Matt Smith shaved his head for a role, they’ll surely get over the former Amy Pond’s new look, especially when she shows how badass she is in ‘Guardians’.

What do you think of the unnecessary hate on James Gunn for Karen Gillan’s new look to play Nebula? Does she pull off the bald look better than Natalie Portman in ‘V For Vendetta’? Share your thoughts in the comments below.

‘Guardians of the Galaxy’ starring Chris Pratt, Dave Bautista, Zoe Saldana, Lee Pace, Glenn Close, John C. Reilly, Karen Gillan, Benicio Del Toro, and Michael Rooker blasts off on August 1st, 2014.
