I am glad you enjoyed it Octopus, and thanks for keeping me company at the premiere!
I arrived at the IMAX around 5.40pm to collect my comp tix, the fans pen were already 4 rows deep and everyone seems especially tall, and at the press end they were on platforms one storey high! Probably got better views up on the roundabout looking down as I noticed some people were. We saw the back of Anna Kendrick (nice dress), saw the director hugging Chace Crawford, Rodrigo Santoro and Matthew Morrison.
The Director introduced the cast before the screening, so we got a brief glimpse of them in the semi-darkness! So we had Chace Crawford (hugged by the Director again!), Rodrigo Santoro, Matthew Morrison, Anna Kendrick, Cheryl Cole and then last and not least Cameron Diaz.
The film was ok, thought it was more a made for TV film, and it took me some time to get into it as it was quite boring. There were a few comedic moments (the little black boy falling over in the park etc - he was so sweet), but overall I did not think it was that funny, the script was weak, and the characters did not gel, and I did not feel for any of them.
I saw an interview on breakfast TV yesterday with Anna Kendrick, and she said it was a no holds barred film, very graphic etc. so was expecting some gruesome birth giving, but it was pretty tame.
[spoiler]But I did like the twist with the stepmother turning out to be really nice and not an "evil" stepmother, and everything was all so perfect for her.[/spoiler]
Don't expect much!

We did get a nice goody bag - but on a hot day would have liked a bottle of water! However, the goody bag is obviously geared for the pregnant woman. All Palmer's cocoa butter products: a big jar of Tummy Butter for stretch marks, a big tube of massage cream for stretch marks, and for the men, cocoa butter with Vitamin E for body and face.
