Suicide Squad was disliked by film critics, but it has gone on to be a box-office success, earning more than $720 million worldwide.

"We were fortunate enough to spend a lot of time with the director of the film, David Ayer," Weaver told Billboard ahead of the soundtrack's release in August. "We really dug in deep with them in the preliminary stages right when they got back from shooting the picture, and we started to identify the various music cues, what the sound of the movie was going to be, what we all felt the music needs of the picture were."

Unlike the hit soundtrack to Guardians of the Galaxy — which had the unifying theme of 1970s music — the Suicide Squad soundtrack featured a cross-generational array of artists such as Twenty One Pilots and Creedence Clearwater Revival.

"Being able to tap into such a wide range of artists, give them assignments, show them footage and connect them into David was a really interesting way to go about the development of the music," said Weaver.
