Lots going on for the CW’s hit show Arrow this weekend: with the show’s Comic-Con panel underway, we’ve already learned a few new things, including the official casting choice of Black Canary. Even if you weren’t able to get into the panel (or aren’t at the convention at all), the CW has made available the lengthy sizzle reel that opened the panel. Check it out below.

The CW and DC Comics released an exclusive sizzle reel for the show during today’s packed panel at Ballroom 20. The three-minute clip is loaded with spoilers, with footage from last season as well as brand new scenes from the upcoming second season. The clip even teases us with the first look at Black Canary, who by the way, will be portrayed by Caity Lotz, who played Anna Draper’s hippie niece Stephanie on Mad Men. We also see the first appearance of Summer Glau as the villainous Isabel Rochev.

Arrow also stars Katie Cassidy as Laurel Lance, Willa Holland as Thea Queen, Manu Bennett as Slade Wilson, Colton Haynes as Roy Harper, Emily Bett Rickards as Felicity Smoak, Susanna Thompson as Moira Queen and Paul Blackthorne as Detective Quentin Lance. Season 2 will premiere on the CW on Wednesday, October 9th at 8 p.m. ET/PT.
