Superhero Hangout! Supergirl, the Flash, Arrow, Superman all hang out on set together while filming a Arrowverse crossover “Elseworlds" episode in Vancouver, Canada. Tyler Hoechlin, Grant Gustin, Melissa Benoist and Stephen Amell seemed to be having a laugh as they waited for the next take. The Arrowverse crossover, “Elseworlds,” includes other iconic DC Comics characters like Superman (Tyler Hoechlin) and Lois Lane (Elizabeth Tulloch), and John Wesley Shipp in a Flash costume. But at the end of the day, the crossover is primarily a topsy-turvy ode to the universe’s main trio: Supergirl (Melissa Benoist), the Flash (Grant Gustin), and Green Arrow (Stephen Amell). #supergirl #superman #arrowverse #grantgustin #melissabenoist #tylerhoechlin Celebrity WotNot videos are copyrighted and owned by © Atlantic Images Ltd.
