During some of the filming, Gwyneth Paltrow stayed in Q staircase of Tree Court, Gonville & Caius College as this was minutes away from the mocked-up old street at the back of Caius.
Sylvia Plath's daughter and literary executor, Frieda Hughes, not only refused to cooperate with the producers or allow them access to her mother's poetry, but also publicly denounced the project in a published poem of her own.
The film begins with the time that Sylvia Plath and Ted Hughes met, and the trees are shown in autumn colors with falling leaves. However, Sylvia and Ted met in late winter, February of 1956, when the trees would have been bare.
