Would you expect anything less than a grade-A bachelor pad from action movie maestro Michael Bay? The blockbuster director's Bel-Air spot doesn't disappoint, and it's one of three estates he's owned in the neighborhood (he's rebuilding one and flipped another last year). Bay has been sitting on this one since '99 fresh off that Armageddon money and has since upgraded it with a state-of-the-art in-home theater, bars, and a wine cellar. The location also boasts unobstructed LA skyline views from Mount Baldy to Santa Monica Bay.
