The Lamborghini Murcielago was named for a bull named for a bat. Bruce Wayne, well, he dresses in a bat-themed costume and calls himself "The Bat-Man." Apparently, Lambo honcho (and dapper man) Stephan Winkelmann felt that the synergy was a fine, fine fit, noting that the company only allows its vehicles to be used in films it likes. The flick, tentatively titled The Dark Knight, drops in '08. No word as to whether the Austin, Texas Ice Bats will be making a cameo.
