"The pic has the शीर्षक of The Suicide Squad and is not being labeled a direct sequel but as a relaunch.

Sources say that Gunn’s focus is to take the franchise in a new direction with a mostly all-new cast of characters and actors. Sources also say that the project is also very much rooted in Gunn’s vibe, as seen in the Guardians movies."
