English actress Sienna Guillory never intended on pursuing an acting career--and with her striking physical beauty and natural charisma, it's no wonder she ended up working first as a professional model. From 1997 to 2000, Guillory found high-profile work in campaigns for the likes of Hugo Boss, Dolce & Gabbana, and Armani (among others), even landing on the cover of numerous magazines including "Vogue." Before and even during this stretch, Guillory had earned minor roles in TV movies and one-off TV episodes, but upon her retirement from modelling in 2000, she became far more serious about a career as a thespian. Fresh from an education at both the Paris Conservatoire and Miami's New World School for the Arts, Guillory took on a variety of eclectic roles in the early decade, including parts in projects like the 2001 comedy-thriller "Kiss Kiss (Bang Bang)," the 2001 rehab drama "Two Days, Nine Lives," and the 2002 sci-fi adventure "The Time Machine," based on a novel by H.G. Wells.
As the 2000s continued, Guillory's roles continued to grow in size and prominence: She appeared (among an all-star cast that included Hugh Grant and Liam Neeson) in the Golden Globe-nominated romantic-comedy "Love Actually." She also found profitable gigs in the video game-adapted sci-fi horror franchise "Resident Evil," appearing in three titles (including 2004's "Resident Evil: Apocalypse"). While her good looks certainly haven't hurt her career, Guillory has more than demonstrated her acting range.
