Tributes have been flooding in for the popular and talented French actor, who has died at the age of just 37 following a skiing accident.
Although his acting career was cut tragically short, he has still starred in some classics of French cinema.
Here are some of his best-known roles.
Les Égarés (Strayed) – 2003
Ulliel was named Best Male Newcomer for his performance as a wild teenager who helps Emmanuel Beart and her young son as they flee Nazi-occupied Paris in this adaptation of Gilles Perrault’s novel Le Garçon aux yeux gris (The Boy with the Grey Eyes)
Un long dimanche de fiançailles (A Very Long Engagement) – 2004
The following year, he won a César for Most Promising Actor for his role in director Jean-Pierre Jeunet’s drama telling the story of a young woman’s search for her fiancé, who disappeared from the trenches of the Somme during World War I.
He had been nominated for the same award in each of the two previous years – including for Les Égarés.
Hannibal Rising – 2007
His first English-language role is perhaps his best-known among anglophones. Based on the Thomas Harris novel, it reveals Hannibal Lecter’s evolution from vengeful Nazi hunter to cannibalistic serial killer.
Saint Laurent – 2014
Ulliel took the lead role in this 2014 biopic of the fashion designer’s life between 1967 and 1976 – when he was at the peak of his influence on haute couture.
He was nominated for a César – losing out to his opposite number in a rival biopic – and won a Lumières Award for Best Actor.
Juste la fin du monde (It’s Only the End of the World) – 2016
Two years after he was nominated for a Best Actor César for the first time for his role in Saint Laurent, the actor won the award for his performance in Xavier Dolan’s gut-wrenching-yet-tender drama as a terminally ill writer who returns home to tell his family his days are numbered. The film also won the Grand Prix at Cannes.
Les confins du monde (To the Ends of the World) – 2018
In this drama set during the First Indochina War, Ulliel plays the only survivor of a massacre in which his brother has perished. Blinded by revenge, he rejoins the forces in search of the assassins – but a chance encounter changes everything.
La vengeance au triple galop – 2021
His most recent performance, as Docteur Danley in this TV movie spoof of the 1980s Australian drama Return to Eden is a bit of a change from his usual fare.
It also stars Audrey Lamy, Marion Cotillard and Alex Lutz – best known as Catherine from the comedy shorts Catherine et Liliane.
He will also feature in the new Marvel series Moon Knight, which is due on the Disney Plus streaming site in March, while director Emily Atef’s life-affirming drama Plus Que Jamais (More Than Ever) is in post-production.
