Yeah maybe. I am a bit out of touch with all the "young" actors and actresses.
I just find it easy if I can picture someone in the movie playing in my head while reading.
Taylor Lautner doesn't seem like a great David for the book but for some reason he is all I could think of that would work for me. Plus he could pull off all the action scenes easily.
And Scarlett, well I wanted David to have the best kick butt bombshell out there right now. She seems perfect for the role, age aside.
If the movie truly gets made I hope we will all be satisfied with the casting choices.
