English to Spanish Art/Literary Art�culo period�stico sobre boxeo

Es un artículo sobre boxeo (de Norman Mailer, 1971).
Patterson tenía fama de ser un caballero, Liston de mafioso, rufián (pero era el campeón del mundo -peso pesado).
"Patterson was appealed to by political blacks to win the Liston fight for the image of the Negro. Responsability sat upon him like a comic cutback in a silent film where we return now and again to one poor man who has been left to hold a beam across his shoulders. There he stands, hardly able to move. At the end of the film he collapses. That was the wieht put on Patterson.

Mi duda es con la frase: ..-like a comic cutback in a silent film where we return now and again to one poor man who has been left to hold a beam across his shoulders...
