7. Fred Astaire
"The history of dance on film begins with Astaire." ––Gene Kelly

Has there ever been anyone as smooth as Fred Astaire, before or since? Pictured here with starlet Ginger Rogers, the dapper entertainer was known for his dancing chops and the series of darling Hollywood musicals they starred in together. Astaire's stage, film, and television careers spanned over 70 years. (!)
