Original Luke Skywalker actor and long-time Joker voice actor, Mark Hamill, has just taken to Twitter to shout out another OG in the animated Batman world — Kevin Conroy.

Having just celebrated the 27th anniversary of Batman: The Animated Series, Hamill took the time to pay homage to Kevin Conroy, aka the voice behind Batman from a plethora of Batman projects, just in time for the Dark Knight’s 80th anniversary. While the two are sworn enemies when it comes to the DC Universe, this tweet shows the respect and admiration the two have for one another when not in character.

Read below for Mark Hamill’s jovial tweet towards Kevin Conroy.
