Seven of Siegfried Sassoon's poems were narrated in the film: Concert Interpretation, Died of Wounds, When I'm among a Blaze of Lights, To my Mother, To my Brother, Attack, and Invocation.
Sassoon quotes Oscar Wilde's famous "love that dare not speak its name". The film features Robbie Ross, Wilde's friend and the man who kept his works in print.
The film starts with a concert featuring The Rites of Spring, considered one of the breakthrough moments in Modernism. Sassoon was a poet who retrospectively became known as a Modernist poet.
Ivor Novello (Jeremy Irvine) is shown singing his comedy song And Her Mother Came, Too. Altman's Gosford Park had Jeremy Northam playing Novello singing this very same song.
