From thundering fighter planes and explosive sets to Shia LaBeouf, Megan Fox, Josh Duhamel and Tyrese Gibson, only ET's Mark Steines is blogging exclusively from director Michael Bay's top-secret 'Transformers: Revenge of the Fallen' set in New Mexico to give you an unprecedented sneak peek at next summer's biggest movie!

'Revenge of the Fallen' crash-lands into theaters June 26 '09 with the reunited cast of the original blockbuster, which saw mankind caught in the middle of battling Autobots and Decepticons from another galaxy. Up until now, the 'Transformers' sequel set has been off-limits, but only ET got complete access to the closed set on Holloman Air Force Base and White Sands Missile Range in New Mexico.

Tune into ET tonight for our all-'Transformers' Tuesday!
