Members of the Krewe of Chewbacchus paraded through the streets in science fiction- and fantasy-themed costumes on Saturday in New Orleans. This year’s parody theme was “Cult of the Sacred Drunken Wookiee.” Krewe members battled with lightsabers through the streets in “Star Wars”-themed costumes and E.T. the Extra-Terrestrial and a 15-foot tall unicorn were among the floats paraded by more than 50 subkrewes.
