Dressed as a Jedi knight, Kendall Gelner sat at the bar in the Alamo Drafthouse Cinema tapping on his mobile device, eagerly awaiting a 7:45 p.m. showing of “The Last Jedi.” “I enjoy dressing up as a Jedi. It’s fun,” said Gelner, 47, of Westminster. Gelner was not alone Thursday night as dozens of costumed Star Wars fans streamed into the multiplex theater on West Colfax Avenue in the Sloan’s Lake area. Missy Gutreuter, 44, hit the theater carpet donning a Princess Leia costume.
