The crew had a limited time window of 30 minutes (director of photography Linus Sandgren said it was exactly between 7.20 - 7.50 pm) within two days to film the magic hour dusky purple twilight Hollywood Hills dance sequence. According to Damien Chazelle, Emma Stone and Ryan Gosling managed five takes in two days, where after each take, they would go back to the starting point with the assistants wiping their sweat before starting the dance routine again. The fourth take is the one used in the final film.
