War for the Planet of the Apes doesn't hit screens until July 14, 2017, which gives you plenty of time to immerse yourself in the lore of the series. So it seems appropriate that ComiXology are currently hosting are hosting a huge sale on Planet of the Apes comics published by BOOM! Studios, with over 50 issues available at reduced prices. But hurry, because the sale ends today!
BOOM's Planet of the Apes series is set in the universe of the original 1968 film and examines the ongoing conflicts on the planet populated by hairy primates. Sales proved to be so successful that it would even have spinoff crossovers with both Star Trek and Tarzan.
