Decoder Ring: Why Do Actors Act Like They Can Sing?

Decoder Ring: Why Do Actors Act Like They Can Sing?

Author: Slate Podcasts September 4, 2026 Duration: 58:12

When an actor opens their mouth to sing in a movie, chances are high that the voice you hear will be their own. Even in music biopics, movie stars without much singing experience regularly go to great lengths to impersonate the most beloved vocalists of our time. Why not simply play Johnny Cash or Bruce Springsteen’s actual recordings, the reasons why we care about them in the first place? When the world is full of beautiful singing voices, why force Pierce Brosnan to bray his way through Mamma Mia?


What you hear when an actor unhinges their jaw is a matter that Hollywood has been negotiating since the dawn of sound. So in this episode, we’ll learn about the “ghost singers” of classic Hollywood musicals, find out why they went extinct, and why today’s music biopics so often fudge the music. Then we leave Hollywood for Bollywood, where the rise of the celebrity “playback singer” shows what can happen when good singing is the highest priority.


In this episode, you’ll hear from Slate’s pop music critic Jack Hamilton; musicologist Dominic Broomfield-McHugh, editor of The Oxford Handbook of the Hollywood Musical; Stephen Cole, co-author of a memoir by the ghost singer Marni Nixon; Isaac Butler, longtime Slate contributor and scholar of American acting; and Nasreen Munni Kabir, who has written several books on Hindi cinema and curates Indian films for the UK’s Channel 4.


This episode was written and produced by Max Freedman. It was edited by Willa Paskin and Evan Chung, our supervising producer. Decoder Ring is also produced by Katie Shepherd. Merritt Jacob is Senior Technical Director.
