No one is going to see it coming.

I dont know what those writers are eating, but its brain food.

Do they fall in love quickly?

Whats going on with that?

Its not going to go over [well], says Hartley.

What do you think its going to be smooth or rocky?

And since were throwing out questions, what is going on with ex-wife-turned-girlfriend-turned-ex-girlfriend Sophie (Alexandra Breckenridge)?

Does she come back [to him]?

I dont know why she would come back.

I think shes probably done at this point.

Does he become a massive celebrity or is the movie a flop?

Its a Ron Howard movie, so its not going to be a flop.

Does he win an award?

Hows he going to deal with that?

Does his sobriety get in the way?

Does it help him?

And what if the movie doesnt do well, how does he deal with that?

Those questions and more will be tackled whenThis Is Usreturns to NBC for season 3 on Sept. 25.

For some hints about the season premiere from creator Dan Fogelman,head over here.
