Josh Brolin And Bryce Dallas Howard Wanted For 2015 "Jurassic Park" Sequel?

So casting for the highly-anticipated "Jurassic Park" sequel is underway. The first batch of rumours have just came in this week. The casting rumours are suggesting that both Josh Brolin and Bryce Dallas Howard are in the running for roles, possibly leads in the 2015 sequel, directed by Colin Trevorrow.
I actually want Brolin to be in something big again because he is such a great actor who doesn't get much good films or many chances at blockbusters franchises to be honest. "Men In Black 3" has been pretty much his only chance at a blockbuster. Bryce Dallas Howard on the other hand.......don't like her. I'd rather see someone else take her role. So hopefully that casting is just a rumour for sure.
Also, it was confirmed a few weeks back that the new "Jurassic Park 4" will be officially called "Jurassic World" instead. The title is extremely interesting in my opinion. Here's the films official logo below.
