Lionsgate have released the latest trailer for the upcoming period drama Ammonite.

The official synopsis for the film is as follows:

In 1840s England, acclaimed but overlooked fossil hunter Mary Anning works alone on the rugged Southern coastline. With the days of her famed discoveries behind her, she now searches for common fossils to sell to tourists to support herself and her ailing mother. When a wealthy visitor entrusts Mary with the care of his wife Charlotte Murchison, she cannot afford to turn his offer down. Proud and relentlessly passionate about her work, Mary initially clashes with her unwelcome guest, but despite the distance between their social class and personalities, an intense bond begins to develop, compelling the two women to determine the true nature of their relationship.

The film, inspired by the life story of palaeontologist Mary Anning, is written and directed by Francis Lee and stars Kate Winslet, Saoirse Ronan, Fiona Shaw, Alec Secăreanu, James McArdle, Gemma Jones, Claire Rushbrook and Harvey Scrimshaw.

Ammonite will premiere in the UK at BFI London Film Festival on the 17th October 2020.
