The CW has unveiled an extended three-minute trailer dubbed "Arrow: The Movie" which actually just shows off the scope of this week's game-changing episode 'The Promise'.
Slade Wilson (aka. Deathstroke) has announced his arrival in Edge City. Now the confrontation is on between former allies turned enemies. Scenes from both already aired episodes and next week's 'Suicide Squad' are also cut in to add more context.
Executive Producer Marc Guggenheim says the episode is "the biggest episode we’ve ever done on the show. It makes the season finale last year look like a student film from the 1980s." One such challenge was recreating the entire deck and bridge of a freighter just for this episode.
