Rob Mills is not a body language expert. He is ABC’s senior VP of alternative series, specials, and late-night programming, and he knows a little bit about thorough preparations for big events such as the Academy Awards ceremonies.
He told Variety that Gaga and Bradley's performance was meant to be in the spirit of A Star Is Born:
[T]he producers really worked step-by-step with them to make that what they were envisioning a reality… this was staying true to the spirit of the movie as well. They really wanted to kind of embody everything that the characters in the movie stood for in this three-minute number.
