The acting duo, who both live in New York, will be appearing in the play at the 499-seat Broad Stage at the Santa Monica College Performing Arts Center from Jan. 11 to Feb. 10.
The play marks the first time Cavanagh and the Tony, Emmy and Golden Globe Award-winner Hirsch have worked together. Cavanagh saw the play off-Broadway before it closed this summer, but Hirsch hadn't seen a production before signing on, though he says he's been lately asked to play Freud several times.
The youthful-looking Cavanagh threw himself into the project. "I researched like crazy, nonstop. Videos, books, articles — I just tore it upside-down," he says.
"I came into the first day of rehearsal and they said, 'You're playing Lewis.' I was like, 'What?' I even had the accent," he jokes. "It just goes to show you — read the emails."
This play may mark the first time they are collaborating, but their chemistry both onstage and off reveals a comfortable collegiality and a willingness to banter.
"This is the first of I'm sure many combinations," says Cavanagh.
Hirsch agrees: "I expect to encounter Tom many, many times in this life."
