Chevrolet's press conference at the 2009 Chicago Auto Show may not have contained production car debuts, but General Motors' volume brand managed to keep things exciting with the unveiling of five Chevy models set to star in the upcoming summer action thriller, "Transformers: Revenge of the Fallen."

Bumblebee will be making a return to this silver screen in the Transformers sequel, taking his familiar form as the Chevrolet Camaro. Although Bumblebee's overall look will be very similar to the first Transformers movie, he does receive some updates for the sequel in the form of a new paint hue, a new hood and unique wheels. Bumblebee's Autobot counterpart is also on display at the Chicago show, towering almost 17 feet over the show floor.

The 2010 Chevrolet Volt will be making its first big screen debut in the next Transformers movie, taking on the role of Jolt. The movie car gives us our first look at the Volt in a color other than its familiar shade of Volt grey.

The Chevrolet Beat and Trax concepts debuted as siblings a few years ago at the New York Auto Show, and the two will once again be reunited in "Revenge of the Fallen", staring as the twin Autobots Skids and Mudflap. Bumblebee's appearance in the first Transformer movie raised Camaro awareness by 97 percent, and GM is hoping for a similar result with the Beat concept, which will make production as the Chevy Spark.

However, the star of Chevy's stage was easily the Stingray concept. Intended to portray what a future Corvette could look like, it remains unclear if the movie car has any actual production intent.
