The CW premiered at SDCC a new three-minute trailer for season two of its hit superhero series “Arrow,” an adaptation of DC Comics’ “Green Arrow,” starring Stephen Amell as the hooded crime fighter and Katie Cassidy as his former flame Dinah “Laurel” Lance.

The trailer gives fans a look at show-killer Summer Glau as mysterious business woman Isabel Rochev and provides an exciting introduction to Dinah Lance’s ass-kicking alter ego Black Canary. No word on whether Cassidy will play Black Canary or if the role is going to Caity Lotz in a new story twist.
