No I think it was alright!

Yes, in Narnia he could pass for a girl. Bit of a tomboy, though.

Totally!
"Believe not what you only wish to believe, but that which truth demands."

Nope, clearly a dude by the time he made We're the Millers. Totally fvck-worthy. Totally.
And please get actors' names right, people. It was Cathy Rigby not Bigby. Moreover she was a major gymnast before turning to acting.

I, too, thought he was a girl for a little while. He is very animateda good quality in an actor.

I'm with Sean.I thought it was girl

Yes, Sean Fisher, you're the only one.
My name is Colin Creevey
and I'm a photoholic.

Are you kidding me? This guy is an round ACE actor!! and his Eustace scrubb was awesome

I don't think the OP was saying anything about his acting. I actually came here myself to see if he was a boy or girl too. I almost knew he was a boy, but every once in a while, he did seem to be a girl. Weird. I find his acting to be very British, which is a good thing. He may be the best part of the movie so far.

If you only knew the power of the Dark Side!

AgreedIf your comment is a complement.
Will Poulter was AMAZING in VDT and although yes he does look young etc I don't think that that is a bad thing. It made him more realistic and as he is in the book.
And haters of the appearence, google him, he looks totally different! goergous! compared to him in role as Eustace.
I'm not trying to be horible or change opinions, but I think people should remember that occaisionaly actors do look themselves up on line and so its a little offensive to keep going on about apearences. Look at talent instead. (This isn't aimed at anyone on this thread so far but i really hope that future posters will think about that and refrain from offending) But yeah, sorry about that, rant over! I just wanted to say!

He was around 15-16 when the movie was filming. But he acted like a 12 year old kid. Which is truly brilliant.
@OP: Go eff yourself.

I'm more shocked that he's 17 years old. He looks like he's 12.

well, i didn't think he was a girl, he just totally acted like one. the single prissiest boy i have ever seen. and don't even get me started on his pig nose.

Cathy Rigby.
And no Will Poulter is not a girl. He just can change his voice to sound very stuck up pre Dragon Eustace and more relaxed post Dragon Eustace. He is an excellent actor!

"Am I the only one"
Well, you're certainly the only one to ever use that line in your title. Very original.

No he has male feature's. Well you could see Cathy Bigby was played by a girl.
