He is best known for directing Hollywood blockbusters full of explosions, but less could be said for Michael Bay's appearance at the Consumer Electronics Show in Las Vegas.
The Transformers director walked off stage during a presentation for Samsung's new curved high definition TV sets, after the auto-cue broke and he felt uncomfortable with "winging it".
Bay was delivering the presentation as a brand ambassador for Samsung, and was due to show a clip from the new Transformers film.
But the action film director soon became flustered during a scripted conversation with the company's vice president Joe Stinziano.
After the auto-cue stopped working, Bay became anxious and started to circle the stage, saying: "The type is all off, sorry, but I'll just wing this."
