In Murder Party, the French Télévisions film adaptation of Agatha Christie's A Murder is Announced, for the Les Petits Meurtres d'Agatha Christie TV series, Philippine Leroy is the parallel of the character Phillipa Haymes in the original novel. Her role in the adaptation is quite faithful to the original. She is a horse trainer working at the ranch belonging to Leticia Salvan. She told her that she was a widow with a young son and wished to rent one of her rooms. In exchange, she offered to help look after and train Leticia's horses. She told Leticia she was lonely and liked horses. Leticia accepted the offer and allowed her to live in the house free of rent as long as she looked after the horses well. Like in the original, Leticia liked Philippine and paid for her son Jean to go to boarding school. Leticia later also made her the sole beneficiary to her estate. The context suggests that this was because Leticia wanted someone whom she could trust to look after her horses after she died.
Like in the original, Philippine was seen giving money to a man in a barn on the morning of Kurt Wengen's death. Philippine however denied that the man was Wengen but would not say who he was. Investigations by commissaire Laurence later reveal that Philippine is not a widow. She is in fact still married to a man who had just finished serving five years for bank robbery. He had come to her that money and Philippine had given him some money.
In the adaptation, Philippine is not the twin sister of Emma, the daughter of Sonia, the lover (sister in the original novel) of the millionaire Denis Sontag (the Randall Goedler parallel). Here Sonia only had one daughter. The character of Philippine Leroy was played by Annabelle Hettmann.
