DC's Legends of Tomorrow is adding a massive guest star into the mix, with Arrow's Stephen Amell suiting up for a big future episode. However, the episode will show a much older Oliver Queen. "We're not only introducing our version of Connor Hawke to our universe, we're going to meet the 2046 version of Oliver Queen, and Stephen Amell is going to be reprising his role from Arrow,” said showrunner Marc Guggenheim​ "As an added bonus to comic-book fans, Oliver is missing his left arm and will be sporting a goatee, in a nod to the character's appearance in the seminal Dark Knight Returns.”
