Modeling Career

Sienna Guillory began her professional journey in the modeling industry. In 1997, she accompanied a friend to the modeling agency Select and was soon signed. Though she appeared in campaigns for luxury brands such as Armani, Burberry, Dolce & Gabbana, and Paul Smith, she later revealed that modeling was primarily a means to support her acting career, rather than a long-term aspiration. Guillory was also featured in several high-profile fashion magazines during this period.

Transition to Acting

Guillory made her film debut in 1993 with a minor role in the television adaptation of "Riders." Despite her success and visibility as an actress, she has stated in interviews that acting was not initially her intended career path, and she had taken roles primarily to earn a living and support her family. During the early stages of her career, she worked part-time as a waitress, an experience she found insightful and formative.

'Resident Evil' and Breakthrough

Sienna Guillory's big break came in 2004 when she portrayed Jill Valentine in "Resident Evil: Apocalypse," based on the popular video game franchise. Her performance in the film raised her international profile and led to further roles in films such as "Eragon" and "Gunless." She reprised her role as Jill Valentine in "Resident Evil: Afterlife" in 2010 and again in "Resident Evil: Retribution" in 2012, cementing her status as a recognizable face in science fiction and action cinema.

Earlier, in 2003, she appeared in the British drama "The Principles of Lust," which generated some attention for its provocative content. Though not her most prominent work, it added to her diverse acting portfolio.
