Miss Morison's Ghosts is a 1981 British supernatural television drama broadcast by ITV starring Hannah Gordon and Wendy Hiller. It is based on a book by two Oxford academics, Charlotte Anne Moberly and Eleanor Jourdain who claimed that in 1901, on a day trip to Versailles, they travelled back in time to the 18th century court of Louis XVI of France, in an event known as the Moberly–Jourdain incident.
