What should the JW trailer look like?

Lets not worry about that yet, there's still about a year and half before the movie comes out, so about a year before any form of trailer.

That said, shot of Nublar, dialogue with some of the characters, and at the end of the trailer, a large shadow looms over the cast before the screen goes black and it says June 11 2015. A roar perhaps would be cool to hear in the trailer at some point.

I wouldn't mind a first teaser trailer similar to the first Jurassic Park III Trailer.

I don't know, there's just lightning and black, with a brief view of the jungle, along with a roar, but that's about it.

I don't think the trailer should give away too much. A quick shot of a foot or set of jaws for example. A roar here or there. Nothing too revealing.

Well for just the first trailer I meant, as a teaser (like the Avengers 2 teaser trailer).  It doesn't give too much away, mainly the title and a small hint at what's going to happen.  The better, more revealing trailers would come later.

That would be cool MrHappy. Nice ideas so far.

No dinosaurs would be boring.  Maybe some quick flashing shots of the new villain and the marine reptiles in there, too.

Frist start from the underwater and then throug the dome and the title shows up,

a short one will be fine right!

I think the teaser should be quite similar to the fake leaked teaser trailer with the Quetzalcoatlus.

What do you guys think?

I expect a teaser trailer like this:

Not very revealing but very cool, the T-rex can be the scary dinosaur.
