- Acclaimed Flop: It had many glowing reviews, but failed to make back its £10 million budget.
- Advertised Extra: Hayley Atwell as a war nurse, due to her established star power, naturally. Taron Egerton's name does not appear at all on some posters for the film, including the one on the main page, yet his character Edward (Vera Brittain's brother) plays a much bigger role than Atwell's character Hope.
- Billing Displacement: This being Taron Egerton's very first studio film to be released (if not shot — the title belongs to Kingsman: The Secret Service) for public viewing, the magnitude of his role in the film is severely underplayed in promotional material. In fact, his character Edward has a greater presence than the top-billed Kit Harington's Roland.
- Fake Brit:
- Swede Alicia Vikander is the lead character, Englishwoman Vera. Downplayed in that Vikander did move to the UK with her family at the age of 15.
- A semi example with Colin Morgan. Though from Northern Ireland, thus a UK citizen, he is playing Englishman Victor, not his native background.
