The reason for this might not actually be his talent, but the fact that Bay, the directorial equivalent of doing cocaine off a stripper's cesarean scar, is the coolest guy these actors have met in a long time. John Malkovich, who appeared in Transformers: Dark of the Moon, excitedly described Bay as "delightful," "fun," and "filled with ideas." To good actors, he's the cool rich kid slumming it with the theater geeks. Sure, he might sometimes yell at the staff or give an atomic wedgie to his assistant director, but when you're part of Bay's VIP circle, the world must feel like you're living in the Entourage opening credits.
More importantly, despite his numerous cinematic flaws, Bay knows how to make his sets awesome. Frances McDormand, who apparently signed on for the third Transformers just to ruin the Not-Megan-Fox character for her teenaged son, was immediately blown away by Bay's energetic masculinity. Everything on set was loud, brash, and sexy -- words you probably didn't hear a lot on the Fargo set. The explosions, the action, and the energy had McDormand running around like a madwoman and she loved Bay for it:
Why couldn't she just hang Shia LaBeouf's actual head?
