Beatrix Potter's "Hill Top" house as portrayed in this movie is actually "Yew Tree Farm" near the town of Coniston (part of the Lake District), which was owned by Potter in the 1930s. You can visit the real Hill Top house which is owned by Britain's National Trust.
Ewan McGregor was Renée Zellweger's first choice to star beside her as Miss Potter's romantic interest, Mr. Norman Warne.
For the scene when Miss Potter and Norman Warne say goodbye at the train station, the script says "exterior rain". Though Ewan McGregor suggested covering the clothes in glycerin to simulate the soaking wet look and to avoid having to actually be drenched, Costume Designer Anthony Powell insisted the actors and actresses be heavily sprayed down for the scene to look authentic. Ewan McGregor was made a very thin wet suit to wear under his costume so he could stay warm.
Costume Designer Anthony Powell sought out all original pieces for this movie, and did not have to reproduce any pieces.
