While some music sensations plunge into movies with fanfare, Courtney Love was as hot as hot could be on the music scene, but decided not to take the spotlighted route of Madonna and Whitney Houston, instead easing her way into the medium with independent pictures. After a handful of small roles, the lead singer of the group Hole found herself in the spotlight when Milos Forman cast her as Althea Leasure in the biopic "The People vs. Larry Flynt" (1996).

 For a world filled with comic book fans, Christopher Reeve had for years been the definitive Superman. For thousands suffering with paralysis and spinal cord injuries, in one tragic moment, he morphed suddenly from an actor perfectly cast onscreen, to a real-life personal inspiration and a champion of medical research and healthcare reform. Standing six-foot-four and sporting a jaw as square as his illustrated predecessor, the then-unknown Reeve became an overnight success when he was cast in “Superman: The Movie” (1978) – most notable for his evenhanded portrait of both the character’s sensitive vulnerability and commanding power in the face of injustice – all the while, wearing tights and a cape. Despite playing such an iconic role, he resisted typecasting in the wake of the film series’ success, sticking close to his original love of live theater when Hollywood failed to deliver worthy scripts.

In the late 1990’s, pop music was overtaken by a stream of teen stars whose good looks, attitude, catchy songs and powerful hype machines often overshadowed their talent--or lack thereof. The anomaly of this teen invasion was Christina Aguilera, who backed up the hype with a powerful set of pipes that validated her pop star status. Possessing a four-octave range, Aguilera faced constant comparison to another blonde ex-Mousketeer, Britney Spears, when vying for the role of pop music’s top diva. Her eponymously titled debut album, released in August 1999, took the music world by storm and eventually sold over 10 million copies. Though she also rivaled Spears and Jessica Simpson as the pop star with the most wholesome image, Aguilera would eventually break that mold to become something she was more comfortable with: herself.

 The third son of actor Martin Sheen, intense, square-jawed Charlie Sheen exploded into the public's consciousness as the narrator-grunt of Oliver Stone's autobiographical Vietnam War picture "Platoon" (1986), a deja vu of sorts that returned him to the Philippines, the scene of his first feature film (as an extra), Francis Ford Coppola's "Apocalypse Now" (1979), starring his father. That performance coupled with his role as Michael Douglas' unscrupulous protégé whose naked ambition leads him into conflict with his blue-collar father (played by his real-life dad) in Stone's "Wall Street" the following year, catapulted him to the status of one of the hottest young actors in Hollywood. Since then, Sheen has worked prolifically, but for much of the 90s, it was his profligacy that earned the biggest headlines and arguably prevented him from fulfilling his early promise.

 A gifted performer who developed her talent at a young age, Cate Blanchett grew into exceptional actress who achieved international acclaim with her stunning Oscar-nominated turn as a young Elizabeth I in Shekhar Kapur’s “Elizabeth” (1998). Prior to that role, the engaging Australian found herself thrust in the spotlight with just her third feature, "Oscar and Lucinda" (1997), starring opposite Ralph Fiennes. As the headstrong proto-feminist heiress whose penchant for gambling draws her to a clergyman with the same predilections, Cate Blanchett delivered a star-making performance that garnered the attention of filmdom’s most esteemed directors. Alluring, yet elusive and possessing an innate intelligence coupled with malleable features – she sometimes seemed plain, but beautiful, often in the same shot – the actress quickly rose to international fame to become one of Hollywood’s most respected and revered talents.

 Striking Canadian import Carrie-Anne Moss, a dark-haired, alabaster skinned beauty, journeyed to Europe to pursue a modeling career, but instead landed on American television, fulfilling a lifelong goal of working as a professional actress. Despite always wanting to be an actress, nothing prepared Moss for becoming a cultural icon when she landed the career-defining role of Trinity, the cool, leather-clad, sunglasses-wearing heroine from the futuristic sci-fi phenomenon, “The Matrix” (1999). So great was the film’s impact on the cultural zeitgeist that Moss become more unrecognizable withoutsunglasses than with. Labeled by media and geek fandom as an action chick—a term she wholeheartedly embraced—Moss was wise in not letting the role define her career and instead balanced her resume with more feminine roles in low-budget indies.

Perhaps no actress had a faster ride to the top than Cameron Diaz, who was launched into stardom with “The Mask” (1994), her first-ever onscreen performance. Though originally slated for a minor role, Diaz won over the movie’s producers with her unique charm and looks, and took on the lead actress role with verve.

When Anna Faris' college roommate first saw Faris in her breakthrough role in "Scary Movie," the ex-roomie called the actress in surprise and told her "That's so weird that you were cast, because you are not funny." Hollywood has continually disagreed with that assessment, casting Faris in several projects where her comedic skills—subtle or, if Faris is to be believed, even unintentional--were allowed to shine.
