Task: Question Answering
Input (English): Passage: In August 2013, Jared Leto told MTV News that he was preparing to shoot a short film for "City of Angels". While he did not reveal much about the music video concept, he added: "It's going to be powerful and emotional and definitely something special." The shooting took place from August 16–17 in Los Angeles, filming multiple monoliths and murals. Leto interviewed celebrities who joined the three members of Thirty Seconds to Mars in sharing their visions about Los Angeles. He also recruited Michael Jackson and Marilyn Monroe impersonators as well as homeless people in the production of the video. After filming, Leto talked about the inspiration behind the video, stating, "Telling stories is a big part of what I do, so it was a really natural and comfortable thing. I think because I did all the interviews myself—I talked to fellow artists and they felt really comfortable. They shared a side of themselves that we don't share very often." Footage from the song's lyric video, which was shot atop the Hollywood Hills, was used for a part of the short film that featured Leto singing the song against the backdrop of a Los Angeles sunset.The short film was produced by Emma Ludbrook, Allan Wachs and Jared Leto, who also directed. Although it is billed as a "Bartholomew Cubbins Film" (Leto's  longtime pseudonym), "City of Angels" is the first directorial project directly credited to Jared Leto. He explained, "It was the first time I'd ever done that. I'd used several different names, but it was just such a personal thing. I thought it was appropriate to put my name on that piece." Previous collaborator Devid Levlin served as director of photography. It was edited by Leto, Benjamin Entrup and Mischa Meyer. The short film included commentary from Kanye West, Christopher Lloyd Dennis, Juliette Lewis, Heather Levinger, Haywood, Lindsay Lohan, Olivia Wilde, Steve Nash, Ashley Olsen, Lily Collins, James Franco, Selena Gomez, Alan Cumming, Anthony Warfield, Jovan Rameau, Holly Beavon, Shaun White, Corey Feldman, and Yosh. "City of Angels" marked the second collaboration of Thirty Seconds to Mars with Kanye West, as they first worked together on the track "Hurricane" (2010).
