Everyone in the images (except for two of the shots in which a different lens was used no doubt) looks a foot or more shorter than they normally do in photographs and are distinctly wider. I suspect a wide angle lens was used here at very close range. The edges of the images were cropped off before publication - there would have been lots to crop off on each side. It makes everyone look husky. Especially Amy Adams and that sucks.
it's true about the distortion - however it looks like the "red carpet/logo wall" area was pretty narrow. Which puts the photographers, depending on their position down the line, in a bit of a bind. They'll each have a couple of options with them, lens-wise and they may not always get a good shot with one or the other camera. The stars are being led down the line by their publicist, stopping every few feet to have photos taken or speak with reporters. All the while the shooters are banging away at everything in all directions trying to get a decent shot while being jostled around by their compatriots. At the end it'll come down to the editor picking from whatever the shooters have on offer. I feel like in this case the "normal" lens options may have been substandard.
