- Completely Different Title: The French release title is My Wonder Women (still in English, somehow).
- Dawson Casting: A 29 years old Bella Heathcote played the 22 years old Olive.
- Fake American: Luke Evans and Bella Heathcote are Welsh and Australian respectively, and both play Americans.
- Elizabeth Holloway Marston was born on the Isle of Man with one American and one British parent, and moved to the US when she was five. Rebecca Hall also had one British and one American parent, but she grew up entirely in the UK.
