During an interview, Olivia Wilde said that the moment in which her character goes naked was an improvisation.
The film joins a select few films that were entirely improvised, such as James McAvoy’s My Son and This is Spinal Tap.
Even though they were provided the main narrative points, the performers wrote the dialogue and all other elements in real time.
The performers were able to develop their personalities more fully and give the situations a more organic flow thanks.
To this creative freedom the fact that the whole thing is improvised may surprise you if you see the trailer.
