An interesting picture has just been posted earlier today by TPAMagazine on Twitter, who are currently taking a tour of Universal Studios Hollywood. The picture is of the "daily shooting schedule" board which is listing (as of January 9th 2011), Desperate Housewives, Parenthood and... Jurassic Park 4. Yes... I'm confused too. Here
is the photograph.
So, how legit is this? I don't know. I don't think just anybody can edit that board which means Universal could be keeping the production of the film relatively quiet, but at the same time why hasn't there been an announcement? It's not normal to have a big film like this not announced and already filming. Joe Johnston finished filming Captain America before Christmas, so it's possible. But I wouldn't get your hopes up for the fact that we've not heard anything and we're used to this kind of thing.
Oh and there is one more photograph
which is apparently the War of the Worlds stage being shot on, suggesting it could be JPIV. We'll just have to wait and see, and I will keep you all updated.
