In the 2008 film "Taken," the surname of retired CIA operative Bryan is Mills.
Bryan Mills is played by Liam Neeson, who portrays a former Green Beret and CIA officer trying to reconnect with his teenage daughter, Kim. When Kim and her friend Amanda are abducted in Paris by human traffickers, Bryan uses his intelligence experience and combat skills to track them down.
The film establishes Bryan’s professional background early, making "Mills" his canonical surname rather than a nickname or an alias. His former colleague Sam Gilroy and his ex-wife Lenore also refer to him as Bryan Mills, confirming the character’s full name.
Released in 2008, Taken became a major turning point in Neeson’s career, transforming him into a prominent action star. The story’s famous phone threat and its 96-hour rescue deadline helped make Bryan Mills one of modern action cinema’s most recognizable characters. The film later produced two sequels and a television series.
