So that's rather gross.
It gets worse. Consider Megan Fox's casting experience for the first Transformers movies, in which she showed up at Bay's house and washed his Ferrari while he filmed it.
This wasn't even the first time she'd been creepily filmed by Bay. When Fox was 15, she was cast as an extra on Bad Boys II for a club scene. At some point during this process, a grown-up explained to Bay that she was only 15 and couldn't be filmed holding a drink. A little hiccup which Bay got around by having her dance around under a waterfall instead. You know. To get soaking wet. When she was in 10th grade.
Possibly because he was annoyed at Fox for pointing out he was an impossible monster, Bay recast her role for the ridiculously-named third film in the series, Transformers: Dark Of The Moon. For that film, he chose English model Rosie Huntington-Whiteley, whose casting consisted of meeting Bay while she was doing a Victoria's Secret photo shoot and answering a single question: "Can you walk?" Huntington-Whiteley managed to exhibit more professionalism than most of us would in the face of such smug douchery, and confirmed that, yes, she knew how to walk. But Bay wasn't done yet. He needed to check this. So right that minute, he drove her half a mile out into the desert, said "Action!" and sped away, leaving her to walk across the desert in heels, underwear, and a floor-length cape.
