There is a short new clip on the official 10 Cloverfield Lane facebook page which contains a new line of dialog by Mary Elizabeth Winstead. The clip also also reveals the name of John Gallagher Jr's character in the movie:
"Emmett, could you hand me the salt."Interestingly, there is an event in the Survival Simulation game that mentions something about "inappropriate behavior" causing morale to drop.
* If anyone has the exact text of that event, please post it in the comments. Thanks!
