Michael Bay’s official message boards Admin ‘Nelson’ has posted an update with info from Bay about Transformers:
1- They will be releasing more teaser posters in the coming months.
2- Paramount made studies and concluded that the TF “ANNOUNCEMENT” was the 2nd highest rated “teaser” this summer.
3.- They just finished shooting a lot of Pentagon interiors on a soundstage in scenes that involved many Chiefs of staff in their huge war room.
4.- Shia just was recently suspended over the edge of a 20 story building in a very dynamic and intense scene.
5.- The average transformation time from normal mode to alt mode and vice versa is about 3 to 4 seconds.
6.- The leaked pictures are legit (although a somewhat early rendering).
7.- Filming of massive chase scenes will begin in the following weeks.
8.- The CGI transformations by ILM are looking wicked and nastier every single day.
9.- Part 1 will be about why the transformers came to earth.
10.- This movie will be a new start for the live action franchise that will not be based on any particular TF TV series and/or comic book.
By the way, the top teaser of the summer was, of course… Spider-Man 3.
