The science-fiction film, directed by Michael Bay, will be in theatres on July 3, 2007.
Just a few days ago, Warner Bros. announced that the film Harry Potter and the Order of the Phoenix would also be opening earlier, now on July 11. The Transformers will now have one extra day to make money at the box offices before the next J.K. Rowling adventure.
The film will not be without competition, however. Bruce Willis returns to his character of John McClane on June 27 in the film Live Free or Die Hard.
