After a violent shipwreck, billionaire playboy Oliver Queen, was missing and presumed dead for five years before being discovered alive on a remote island in the North China Sea by two men on a fishing boat.

 * Although Katie Cassidy is billed as "special appearance", she is still considered to be a main cast member, according to TVLine.
 * Season 8 would've been the first since Season 2 to feature two episodes named after songs by Bruce Springsteen including the penultimate episode that's been a tradition in almost every season.

In addition, the backdoor pilot for the proposed spinoff Green Arrow and the Canaries was created after The CW asked Marc Guggenheim to make one more episode despite being aware that Stephen's not in all the episodes due to his deal when the episode order was going to be nine instead of ten.
