James Gunn making a Suicide Squad movie has felt right since the beginning thanks to his stellar take on Marvel's Guardians of the Galaxy. We've seen set photos and had tons of casting news, but we'll finally have our first trailer tomorrow.

The director took to Twitter with a simple message: "Tomorrow. Trailer. See you there. #TheSuicideSquad" with a picture of a "red band" trailer card.

Gunn wrote and directed The Suicide Squad. Margot Robbie will reprise her role as Harley Quinn, and a few other actors will return as well. Jai Courtney will once again appear as Captain Boomerang, Joel Kinnaman as Rick Flag, and Viola Davis as Amanda Waller. The film also features Idris Elba as Bloodsport, John Cena as Peacemaker, David Dastmalchian as Polka-Dot Man, and James Gunn stalwarts Michael Rooker and Sean Gunn.
