FRIDAY 9/20-SUNDAY 9/22. Hot Springs Convention Center. $10-$125.
If you’ve ever longed to sip the finest glass of beer in Arkansas (it’s the “Beez Kneez” honey basil Kolsch at Superior Bathhouse Brewery, FYI) as a gang of giant robots wanders by, here’s your chance, because the people watching in Hot Springs — seemingly already at its peak quotient of quirk — is about to get off-the-charts nerdy. For this year’s Spa-Con, guests include actor Barry Bostwick, who played Brad Majors in “The Rocky Horror Picture Show” (1975), and who joins Spa-Con for a screening of the film; actor Michelle Harrison (of The CW’s “The Flash”); Cybertronic Spree, a rock outfit that dons flawless Transformers costumes and plays hits from video games, film and anime tunes (also, not incongruously, Zeppelin); illustrators Pat Moriarity, Walden Wong, Sam de la Rosa, Chad Maupin, Nikki Dawes, Stacy Bates, Gustav Carlson, Timothy Lim, Kody Sandwich and others; cosplayers Akakioga, Utahime, Legendary Rose, Arkansas Iron Man, Gregory Harris and an uncannily Nimoy-esque Spock impersonator named Spock Vegas; and Thomas DePetrillo of Extreme Costumes and his giant robots Bumblebee, Hulkbuster and Reinhardt. There’s a Star Wars-inspired Imperial March featuring the storm troopers of the 501st Legion Diamond Garrison, a Tinker Studio from the Mid-America Science Museum, a laser tag arena, a Smash Bros. video game tournament, a cosplay contest and a Spa-Con 2K and 5K Fun Run that kicks off at 9:30 a.m. Saturday morning in front of the Hot Springs Convention Center.
