<P> Hasbro became more involved in the designs of the robots than the company was for Transformers . The company, along with Takara Tomy, suggested to the filmmakers that combining robots be the main draw for the sequel . They insisted on keeping the alternate modes of some of the returning characters similar so that consumers would not have to buy toys of the same characters . Bay used real F - 16 Fighting Falcon and tank fire when filming the battles . Many of the new Autobot cars supplied by General Motors were brightly colored to look distinctive on screen . Revenge of the Fallen features 46 robots, while the original movie had 14 . </P> <P> Scott Farrar returned as visual effects supervisor and anticipated moodier use of lighting as well as deeper roles for the Decepticons . He stated that with the bigger deadline, post-production would become a "circus". The producers expected that with a bigger budget and the special effects worked out, the Transformers would have a larger role . Peter Cullen recalled, "Don Murphy mentioned to me,' Only because of the tremendous expense to animate Optimus Prime, he'll be in just a certain amount of (Transformers).' But he said,' Next time, if the movie is a success, you're gonna be in it a ton ."' Michael Bay hoped to include more close - ups of the robots' faces . The heads had to be designed with more pieces in order to express emotions in a more convincing way . Farrar said the animators implemented more "splashes and the hits and the fighting on dirt or moving, banging into trees, (...) things splinter and break, (the robots) spit, they outgas, they sweat, they snort ." Shooting in the higher resolution of IMAX required up to 72 hours to render a single frame of animation . While ILM used 15 terabytes for Transformers, they used 140 for the sequel . Particularly problematic effects were the lighting, with scenes such as Jetfire inside the Smithsonian requiring 41 light sources, and the destruction of the pyramid, which appears in about five shots and required seven months to simulate the behavior of the blocks . Orci hinted the majority of the Decepticons were entirely computer - generated in both robot and alternate modes, making it easier to write additional scenes for them in post-production . Rendering the Devastator took over 85% of ILM's render farm capacity, and the complexity of the scene and having to render it at IMAX resolution caused one computer to "explode". </P> <P> The score to Revenge of the Fallen was composed by Steve Jablonsky, who reunited with director Michael Bay to record his score with a 71 - piece ensemble of the Hollywood Studio Symphony at the Sony Scoring Stage . Jablonsky and his score producer Hans Zimmer composed various interpretations of a song by Linkin Park called "New Divide" for the score . </P> <P> An additional $150 million was spent to market the film globally . Hasbro's Revenge of the Fallen toy line included new molds of new and returning characters, as well as 2007 figures with new mold elements or new paint schemes . The first wave was released on May 30, although Bumblebee and Soundwave debuted beforehand . The second wave came in August 2009, which introduced toys such as 21⁄4 - inch human action figures that fit inside the transforming robots, and non-transforming replicas of the cars that can be used on a race track . Product placement partners on the film include Burger King, 7 - Eleven, LG phones, Kmart, Wal - Mart, YouTube, Nike, Inc. and M&M's, as well as Jollibee in the Philippines . General Motors' financial troubles limited its involvement in promotion of the sequel, although Paramount acknowledged with or without GM, their marketing campaign was still very large and had the foundation of the 2007 film's success . Kyle Busch drove a Revenge of the Fallen decorated car at Infineon Raceway on June 21, 2009, while Josh Duhamel drove a 2010 Camaro at the Indianapolis 500 . At the movie's launch in China, a version of Bumblebee was constructed using a Volkswagen Jetta . </P>
