Megan Fox in "Transformers"
Though Megan Fox's role in the iconic Transformers franchise catapulted her to global stardom, she was pretty open about her less-than-positive experience on set—revealing to Wonderland magazine that she had a terrible time working with director Michael Bay.
"He's like Napoleon, and he wants to create this insane, infamous madman reputation," she said. "He's a nightmare to work for." Bay's displeasure with Fox's comments led to her very public firing from the series.
