In two weeks, the Arrow-verse is taking over Comic-Con International. For the ninth year in a row, Warner Bros. will sponsor the key card artwork for all SDCC hotels, which will feature fan-favorite characters like Green Arrow, The Flash, the Winchester Brothers, Sheldon Cooper and more. Warner Bros. is sponsoring 40,000 branded room keys at 40 SDCC official hotels.

Arrow, The Flash, Supergirl and DC's Legends of Tomorrow will get a whole keycard to themselves. Supernatural, on the other hand, will boast two separate keys with different artwork. Westworld and The Big Bang Theory will also make a showing on their own individual key cards.
