Saturday at San Diego Comic-Con saw the reveal of trailers for each of The CW's DC properties. With Flashpoint touching all parts of the Arrow-verse, each series debuted sizzle reels that start off with a bang. The Legends of Tomorrow trailer had a big surprise as the team come face to face with former Arrow baddie, Damien Darhk.
Other than the Marvel Cinematic Universe, there's no other umbrella property that shares so much talent amongst its entities. Warner Bros. TV is operating with an exponentially expanding and unified Arrow-verse as contracts get bigger and more encompassing for their actors. Wentworth Miller was the first to ink a deal that made him a series regular across the Arrow-verse; that means his Leonard Snart/Captain Cold character now has the freedom to appear on Legends of Tomorrow, Arrow, The Flash, and even Supergirl if the stories called for it. More recently, John Barrowman (Malcolm Merlyn/Dark Archer) and also signed a similar deal.
TV Line reports that Katie Cassidy can now add her name to this expanded contract list. She, too, has now signed on as a series regular across all Arrow-verse shows.
Arrow is quite fond of flashbacks, so it is highly likely that we will still see a lot of Laurel Lance in one form or another on this show. But Laurel's doppelganger from Earth-2, Black Siren, has already made a name for herself on The Flash. With Sara Lance, her sister, as a lead on Legends of Tomorrow, it wouldn't be far fetched for the time travelers to come across some variation of Laurel as well. Cassidy is also expected to make an appearance (in a flashback) in the season five premiere of Arrow.
Other than the ability to move between series', it is unclear what kind of dollar amounts or stipulations are attached to these Arrow-verse series regular contracts. Whatever the case may be, these new deals are becoming more frequent, and it will be interesting to see how producers and writers will utilize these free range actors in their upcoming seasons. Pretty soon, we won't be referring to CW's Arrow-verse shows individually because they will merge into one four-hour show broken up over four days. Which, if they play their cards right, could make for a great television premise.
The Flash season 3 will premiere Tuesday October 4th at 8pm on The CW; Arrow season 5 will premiere in the same time slot on Wednesday October 5th; Supergirl season 2 on Monday October 10th; and Legends of Tomorrow season 2 on Thursday October 13th.
