Liaison is a British-French thriller television series written by Virginie Brac, directed by Stephen Hopkins and starring Vincent Cassel and Eva Green.

In June 2021, it was announced that Apple TV+ had greenlit Liaison, marking the platform's first "Anglo-French" production.

Stephen Hopkins is directing, Virginie Brac is writing, and Gub Neal and Jean Benoit Gillig are executive producing.

Also cast were British actors Peter Mullan, Daniel Francis, and Bukky Bakray and French actors Gérard Lanvin, Stanislas Merhar, Philippine Leroy-Beaulieu, Laëtitia Eïdo, Eriq Ebouaney and Thierry Frémont.

The website's consensus reads: "More tedious than it is dangerous, Liaison generates some spark from Vincent Cassel and Eva Green's pairing but generally underwhelms as an anemic addition to the espionage genre."
