LAS VEGAS -- "Transformers" director Michael Bay says he's embarrassed that he walked off the stage during a presentation of Samsung's new curved ultra-high-definition television.

Video of the cringe-worthy incident at the International CES gadget show in Las Vegas circulated on social media sites late Monday and early Tuesday. In a statement posted online and confirmed by Bay's production company, Bay says: "I guess live shows aren't my thing."

The video shows Bay start to speak, then stop when the presenter speaks. Bay resumes speaking, then stops again, saying the teleprompter isn't working correctly.

Bay and the presenter then attempt to talk off-the-cuff about the 105-inch TV, but the flustered director apologizes and abruptly leaves the stage.

Bay directed the first three "Transformers" movies, with "Transformers 4" due in theaters in June 2014.
