LOS ANGELES (Reuters) - Powerhouse Hollywood director Michael Bay, who returns to theaters worldwide on Wednesday with a “Transformers” sequel, has blasted the marketing efforts of the film’s studio, Paramount Pictures.

In a memo sent last month to top brass at the Viacom Inc unit, and published on Sunday by celebrity gossip Web site TMZ.com, Bay complained there was no buzz surrounding “Transformers: Revenge of the Fallen.”

 “Right now we are not an event. We are just a sequel, which is very different. There is no anticipation. Remember back to ‘Spider-Man 2′ — it was everywhere,” he wrote.

Bay added that advance word on the $200 million robot extravaganza in publications like Entertainment Weekly, the Los Angeles Times and the New York Times had been an “abject failure,” and he described as “lame” a plan for him to preview a small clip at the MTV Movie Awards this month.
