"Arrow" executive producer Marc Guggenheim has posted an exciting piece of concept art from Arrow's fourth season, referencing Green Lantern's return.
Guggenheim had previously claimed that plans for a Green Lantern Corps movie would prevent Hal Jordan from materialising, reported Digital Spy.
The image - which appears to be a mock tourism promo - even adapts the Lantern's iconic 'In brightest day, in blackest night...' catchphrase.
"Arrow" returns to The CW on October 7 in the US.
