Portrayals
In Murder in Three Acts (1986), the parlourmaid's name was changed to Rosa and the part was played by Claudia Guzmán. Here she had a larger role than in the novel. Besides serving the dinner she also went down the tunnel whose secret entrance was in the library. In the middle of the tunnel, she encountered Poirot and Hastings. She told the two that it was a passage she frequently used to leave the house to go to the restaurant at the other end to meet her boyfriend. On the night the doctor had died, she had gone to the library to use the tunnel but heard footsteps approaching so she went away quickly. The footsteps sounded like a woman wearing short heels. This turned out to be Janet Crisp who had been intrigued about the existence of a tunnel in the house and was searching for it.

In the film adaptation of Three Act Tragedy in Series 12 of ITV's Agatha Christie's Poirot drama series, the name of the parlourmaid was changed to Annie and the part was played by Jodie McNee. Here she also served the dinner together with the butler "Ellis". She was interviewed by Sir Charles Cartwright and Poirot.
