Attracted to the theater from an early age, Anaëlle Othenin-Girard was spotted at the age of 14 in one of her classes, to play the lead role in the film "Simon & Theodore" by Mikael Buch. This first film role gave her the desire to continue in this direction. In 2018 and 2019, she then filmed several films: "Venice Calling" by Ivan Calbérac, "The Vets" by Julie Manoukian, "The Fantastic Journey of Margot & Marguerite" by Pierre Coré, and "Man Up!" by Benjamin Parent, which allowed her to be selected among the César Revelations 2021. We then saw her in "All Aboard" by Benjamin Euvrard, "Family Swap" by Jean-Patrick Benes and "Colors of Fire", a historical drama directed by Clovis Cornillac. In 2025, she announced her coming out as a transgender woman and made her first name change official.
