Godzilla!

I would say 'Probably', but there's no way of knowing for certain.

So did i espicially at the beggining  the film the opening creits

The opening credits music was pretty well done and in sync with the screen.....but it's not really a theme. 

I'm not sure if they will keep Desplat as the composer on any future sequels. He's kind of a B+ grade composer, but this movie has proved the franchise worthy of an A lister's attention. 

And even if they do keep him, I do hope they redo the music. It just wasn't very memorable for me.
