Well like everyone born in the eighties, I was a big fan of the original transformers (more than meets the eye!) series, and watched/bought The Transformers movie (the one with Unicron, which was pretty tight). Still have it now, except on DVD. But now a modern and somewhat "darker" take on it by Micheal Bay and Steven Spielburg is coming out July 2007. Check out the trailer/teaser here:

I really hope this turns out to be as good as the War of the Worlds remake Spielburg did.
