I ask you, what the fuck?
Now I don't usually like to point out things like this because it's a load of crap, but it's so bloody obvious here that it's impossible not to mention it.
And it's not just some strange error in lighting because, look, JP's free from the curse:
In the same series of shots, Albie's looking like Noddy, and AB's head is proportionately huge compared to the rest of his body.
It's almost sickening to watch.
