Baye is among a number of well-known figures who have lived with Lewy body dementia, including actors Robin Williams and Estelle Getty, as well as American radio and television host Casey Kasem.

A major force in French cinema, Baye appeared in more than 100 films and became one of the country’s most respected performers. She won four César Awards, the French equivalent of the Oscars, including an extraordinary three consecutive wins in the early 1980s.

She gained global recognition later in her career, playing Leonardo DiCaprio’s mother in Catch Me If You Can, directed by Steven Spielberg, and more recently appearing as a French aristocrat (Madame de Montmirail) in Downton Abbey: A New Era.

The film was generally well received by critics and went on to earn $92.7 million at the global box office.

Left school at 14
Born in Normandy in 1948 to artistic parents, Baye left school at 14 and first pursued dance before eventually discovering acting.

She had difficulties in school due to dyslexia and dyscalculia, which led her to leave education early. She then moved to Monaco to study dance, a step that would later set her on the path toward her acting career.

”I was brought up with very few rules, so that what rules there were I really respected. I was sensible and well-behaved, actually. Certainly compared to some of my schoolfriends,” Baye once told The Guardian.

Her breakthrough came in the 1970s when she began working with some of France’s most influential directors, including François Truffaut, Jean-Luc Godard, and Maurice Pialat.

She earned critical acclaim for roles in films like The Return of Martin Guerre and La Balance, the latter winning her a César Award for Best Actress. Over the years, she built a reputation for emotionally rich performances and a commanding screen presence.

Beyond her professional life, Baye had a high-profile relationship with French rock icon Johnny Hallyday, and their daughter, Laura Smet, followed in her footsteps to become an actress.

Baye is survived by her daughter and grandson. Close friends and collaborators have also been deeply shaken by the news. Among them was director Thierry Klifa, who had been one of Baye’s closest friends for 25 years. Speaking to Le Parisien, he reflected on their enduring bond and described their friendship as unbreakable.
