Transformers attraction coming to Universal Studios Hollywood
Nov 2, 2008

Universal Studios Hollywood will be opening a Transformers themed attraction in 2011. This latest thrill ride will feature 3-D high definition, robotics and special effects.

Transformers will be replacing Backdraft and the Special Effects Soundstage. Industry insiders estimate the cost will exceed the Simpson's $40 million price tag. The Transformers attraction is also scheduled to be built at Universal Studios Singapore and will make its debut prior to its LA counterpart.

Construction on Transformers is scheduled for Fall of 2009 following the summer release of the Transformers movie sequel.
