Which actress is commonly associated with the glossy mainstream films of the 1950s?

Grace Kelly is often recognized as the quintessential leading actress of the glossy mainstream films of the 1950s. She starred in several high-profile, glamorous films during this decade, often portraying characters that embodied elegance and sophistication. Her performances in major works such as "Rear Window" and "Dial M for Murder," both directed by Alfred Hitchcock, showcased her ability to captivate audiences with a blend of poise and emotional depth.

Kelly's image was tightly woven into the luxurious and polished aesthetic characteristic of the era's cinema, making her synonymous with the glamorous lifestyle that these films often depicted. This association helped elevate her status to that of a major cultural icon during the 1950s. Other actresses from that time, like Audrey Hepburn and Marilyn Monroe, also played significant roles in film, but Grace Kelly's specific contributions align more closely with the themes and styles that defined the glossy mainstream productions of the decade.
