Everybody Does It is a 1949 comedy film starring Paul Douglas, Linda Darnell and Celeste Holm.
In the film, a businessman's wife tries to become an opera star. Although she fails in her initial plans, she meets some interesting figures and has a wonderful time.

Linda Darnell's character sings long, beautiful stretches of an imaginary opera, L'Amore di Fatima. The music for it was written by Mario Castelnuovo-Tedesco. In a little tongue-in-cheek detail, the poster for the opera lists Tedesco – who also wrote real operas — as the composer. To add to the illusion of the opera's authenticity, Paul Douglas also sings some known songs, including a musical setting of the Rudyard Kipling poem Mandalay and the Toreador Song from Carmen. The operatic scenes were staged by Vladimir Rosing.
