Dreyfuss will play Joe Keller, a father with a guilty secret about his two sons, one killed in WWII, the other one questioning the nature of his sibling's death. Clayburgh will play his wife, Kate, who stands by him despite mounting evidence of his guilt.

Clayburgh appeared with Dreyfuss in The Exonerated Off-Broadway. In the early '70s, she starring in the original Broadway companies of The Rothschilds and Pippin. Later, she appeared in Design for Living as Gilda, opposite Raul Julia and Frank Langella. She is still well remembered for a string of films in the '70s, including "An Unmarried Woman," "Silver Streak" and "Starting Over."

Dreyfuss has booked a lot of theatre of late. In New York, he's done a brief stint in Off-Broadway's The Exonerated and is set to put in a one night-only appearance in Trumbo at the Westside. All My Sons, which runs Aug. 6-23, would mark his most sustained engagement to date.

Artistic director Joanne Woodward said in a statement, "I saw Richard in a show called The Exonerated in New York. His biography in the playbill said that he was 'looking for a good play' and when Doug Hughes mentioned Richard for the role, I thought, 'it looks like he's found one.'"
