"It Will Rain" is a song by American artist Bruno Mars. The song was released on iTunes for purchase on September 27, 2011. An accompanying music video was planned to premiere on October 26, 2011 on MTV; however, on October 24, 2011 Mars announced via Twitter that the music video had been delayed for several weeks. It eventually premiered on November 10, 2011. The track appears on the soundtrack to the film The Twilight Saga: Breaking Dawn – Part 1.
Skylar Grey performed the song with Mars during his live tour of Europe.
"It Will Rain" is a love ballad co-written and produced by Bruno Mars and his songwriting and production team, The Smeezingtons. The Breaking Dawn – Part 1 soundtrack was released on November 8, 2011. Mars described the song as concerning "the darker side of love". Mars and his label Elektra Records later celebrated achieving his fourth #1 single on the Billboard Top 40 chart with "It Will Rain".
"It Will Rain" is featured in the end credits of The Twilight Saga: Breaking Dawn – Part 1. Mars said the tune was halfway done before he viewed an early cut of the film and, inspired by its characters, put together the finishing touches. Alexandra Patsavas, music supervisor for the Twilight films, said she picked Mars because Part 1 centered on a wedding and, "Who more appropriate than Bruno Mars to write a timeless, classic wedding song?"
Mars later remarked he had to "turn off the radio" upon hearing the final mix of his vocals on the song, saying "I felt like I was a mosquito singing. I don't want that to happen again."
The agony and torment of heartbreak in the lyrics describe the universal emotional pain of relationship bonds like morphine relationships, sexual arousal, bonding and romantic attachment and behavioral addiction, being ripped apart that results in depression. Although some reviews were mixed, for example Rolling Stone, which gave the song three stars out of five, saying it "sounds a little bit like "Wild Horses," and "a lot like Mars' next radio juggernaut".
The music video for "It Will Rain" premiered on November 10, 2011 on MTV. Mars falls for a girl in the clip and it shows the pair going through different emotions like love and anger. It also features footage from the film Breaking Dawn: Part 1, the fourth film in the Twilight saga. The video for the song was then uploaded on YouTube by Mars' label Elektra Records.
