Celebrated actors Don Cheadle and Ayo Edebiri are both making their Broadway debuts in a revival of David Auburn’s Tony- and Pulitzer Prize-winner “Proof,” about a brilliant mathematics professor with mental-health issues, and his daughter with issues of her own. Cheadle and Edebiri talk with Tracy Smith about exploring the dynamics of a parent-child relationship, and how their off-stage relationship helps them on-stage.
