5. Carol Channing in "Gentleman Prefer Blondes" and "Hello Dolly!"
The two signature Broadway roles that brought fame to Carol Channing (pictured) were both adapted to the screen and recast with different actors. In 1949, Channing gained recognition with her first lead role as Lorelei Lee in “Gentlemen Prefer Blondes,” which was adapted as a film in 1953 starring Marilyn Monroe. Channing went on to originate the role of Dolly in the 1964 Tony Award-winning musical “Hello, Dolly!” While “Hello, Dolly!” faced competition from Barbra Streisand’s musical “Funny Girl” in its opening year, Streisand was cast as Dolly in the 1969 film adaptation. Streisand may have taken Channing’s role on screen, but Channing stole the Tony for best actress that year! (Photo by Getty Images)
