IndieWire caught up with Mark Ronson, who worked alongside Lady Gaga and Bradley Cooper for the A Star is Born soundtrack where he talks about the evolvement of Shallow.
The song was originally written about drowning and then eventually evolved into the powerful anthem about love and filling the void personally and professionally.
“Gaga was writing from the standpoint of Ally as an end credit song, because in the original script Bradley’s character drowns,” said co-writer Mark Ronson.
“But somehow Bradley decided that they were going to work it into the script as a duet. It’s a really good song that the movie turned into a really great song, and that’s the best you can hope for.”
Ronson liked the unconventional structure of three verses interspersed with the chorus. “It’s like a dialog between them,” he added. “It’s unpredictable and builds to something exciting.”
