- Alternative Character Interpretation: This is discussed in the film itself between certain characters, some of which think that Marilyn is genuinely sweet and innocent, whilst others accuse her of knowing "exactly what she's doing" when she keeps everyone waiting for hours and runs off without telling anyone where she's going.

- Retroactive Recognition: For those who didn't know Eddie Redmayne before this, this is likely to be enforced following his performance as Marius in Les Misérables (2012), and as the third Harry Potter alumnus in this movie after Emma Watson and Kenneth Branagh, thanks to Fantastic Beasts and Where to Find Them.
- Tear Jerker: "Why do the people I love always leave me?"
