It's been confirmed this week that the cast of "Transformers" will be hitting the windy city in July to film the third installment of the ever so successful "Transformers" movies.

Megan Fox, along with co-stars, Shia LeBeouf, Josh Duhamel, Tyrese Gibson and Frances McDormand, will spend approximately six to seven weeks filming in Chicago.

Rich Moskal, Chicago Film Office Director called the upcoming big-budget shoot "a blockbuster in every sense of the word in terms of economic impact, stunts and special effects."

Fox and her colleagues are expected to begin shooting along Michigan Avenue and throughout the Loop on July 4th.

But a few weeks before "Transformers 3" will occupy space in the Chicago Film Studios where they can begin to construct sets, get wardrobe organized, and create office spaces for the big blockbuster shoot.

"T3" will shoot in six other world cities in the continuing saga of the admirable Autobots and dastardly Decepticons, who disguise themselves by transforming into everyday machinery," said Moskal.

"Transformers 3" is scheduled for a July 1, 2011 release.
