Comedy icon Will Ferrell is nearly impossible to recognize after undergoing a jaw-dropping makeover while on the set for “The Fifth Wheel,” starring Kim Kardashian and Nikki Glaser. Ferrell turned heads in a wild getup: chin-length blonde locks, a braided goatee, dramatic black eyeliner, a glittering black-and-red vest with billowing chiffon sleeves, and fringe-heavy leather pants. Directed by Eva Longoria , “The Fifth Wheel” is a comedy that tells the tale of a disastrous trip to Las Vegas.
