Marlon Brando usou cottonballs, então eu sugiro que eles não sejam muito moles. Eu acho que foi mostrado em Hearts of Darkness e mencionado em The Godfather commentary, que são difíceis de linkar por razões óbvias.
De O wikia Padrinho :
Brando's performance as Vito Corleone in 1972's The Godfather was a mid-career turning point. Director Francis Ford Coppola convinced Brando to submit to a "make-up" test, in which Brando did his own makeup (he used cotton balls to simulate the puffed-cheek look).
Eu pessoalmente já tentei, e é preciso algum tempo para se acostumar, mas com um pouco de prática você pode fazer com que o algodão permaneça no lugar. O arrastar lento e metódico de Brando pode ser porque ele estava trabalhando com esse handicap. Talvez bolas de algodão mereçam um Oscar honorário.

Jaffe eventually set three conditions for the casting of Brando: That he would have to take a fee far below what he typically received; he'd have to agree to accept financial responsibility for any production delays his behavior cost; and he had to submit to a screen test. In order to skirt the humiliation of having Brando submit to a screen test, Coppola convinced Brando to a videotaped "make-up" test, in which Brando did his own makeup (he used cotton balls to simulate the puffed-cheek look). Coppola had feared Brando might be too young to play the Don but was electrified by the actor's characterization as the head of a crime family. Even so, he had to fight the studio in order to cast the temperamental actor. Brando had doubts himself, stating in his autobiography, "I had never played an Italian before, and I didn't think I could do it successfully." Eventually, Charles Bluhdorn, the president of Paramount parent Gulf+Western, was won over to letting Brando have the role; when he saw the screen test, he asked in amazement, "What are we watching? Who is this old guinea?"
