Barbie-elokuvasta on jäänyt mieleen muun muassa tanssi I'm Just Ken, jossa kunnostautuvat niin Ryan Gosling kuin Simu Liu. Ohjaaja Greta Gerwig sai kuitenkin taistella, että jakso mukaan saatiin.
BFI London Film Festivalilla mukana olleen Gerwigin kommentista puhui Variety, jonka mukaan tanssin mukaan saaminen edellytti taistoa johtoportaan kanssa.
"It just said in the script, 'And then it becomes a dream ballet and they work it out through dance. There was a big meeting that was like, 'Do you need this?' And I was like, 'Everything in me needs this.' They were like, 'What do you even mean? What is a dream ballet?' And I was like, 'A dream ballet? Where do I begin!'"
"Even though everything felt right to me and was giving me so much joy in the way we were doing it, it was also like, 'Oh no, this could be just terrible, but now I'm committed'."
