5. Scarlett Johansson (The Island)
Michael Bay has certainly proven himself adept at casting super-hot leading ladies over the years, and one of his smartest picks was in casting Scarlet Johansson as sexy clone Jordan in The Island. The surreal imagery of the opening scene, showing Johansson aboard a boat bathed in lush, ethereal light, demonstrates quite how much the camera loves her, and how much Bay's visual sensibilities complement her physical attractiveness. Of course, this transpires through to the film, too, which has Lincoln (Ewan McGregor) and Jordan trying to flee the island while inevitably hooking up with one another. That said, Scarlet has repeatedly said in interviews that she was happy to go naked for the film's sex scene, but Bay, knowing he had to secure a PG-13 rating, forced her to remain clothed. Could he not have at least shot the scene and released it online as a deleted scene? Such a woeful lack of foresight suggest that perhaps he's not a genius after all...
