The Oscar-nominated film depicts King George VI as a reluctant leader tortured by his stuttering. But with a sense of duty as England confronts a second world war, he musters the courage to seek speech therapy so he can address and calm an anxious nation.
Those who stutter said they can really identify with the film and that they're glad it is bringing the stigma out in the open.
Stuttering affects almost 1 percent of the global population, including 3 million in the United States. It typically begins in early childhood and is more common in boys. Most people eventually outgrow it.
Jane Fraser, president of the Stuttering Foundation of America, said the movie mirrors her experience growing up with a father who stuttered.
