Arrow
Stephen Amell as the Green ArrowThe CW

In November 2015, Arrow star Stephen Amell teased that fans might get to see the classic comic book look of Green Arrow (with the trademark goatee) in upcoming show, Legends Of Tomorrow. Now, executive producer Phil Klemmer has confirmed it. According to Klemmer, older as well as younger versions of Arrow and The Flash will feature in Legends.

Entertainment Weekly reports, there is a "100 percent chance" that older and/or younger versions of Oliver Queen (Stephen Amell) and Barry Allen (Grant Gustin) will appear [on the show]. "We will have a couple marked crossover moments that hopefully will keep people satisfied," said Klemmer.

In 2015, Arrow and Legends actress Caity Lotz (who plays Sara Lance) sent out some tweets indicating that fans will be seeing Oliver as an older man in the spinoff series, which led Amell to post the following cryptic tweet:

DC's Legends Of Tomorrow will premiere on 21 January at 8pm ET on The CW. Arrow season 4 returns after its midseason hiatus, with episode 10 titled Blood Debts, on 20 January 2016.
