There is a secret trailer attached to Iron Man 2. It is for a movie written and directed by JJ Abrams. It is produced by Steven Spielberg.
It is called Super 8.

The new WWII mini series by Steven Spielberg and Tom Hanks. Band of Brothers is probably the best TV mini series I've ever seen so I'm really looking forward to seeing if this one is even better.
