No, that’s not Sigmund you’re looking at, it’s Theatre 3 founder/artistic director Jac Alder in a rare acting role playing the father of psychotherapy in Freud’s Last Session, where he confronts his own mortality (and his atheism) in a session with Christian novelist C.S. Lewis (Cameron Cobb). The show opens tonight.

DEETS: Theatre 3, 2900 Routh St. in the Quadrangle. Tonight at 7:30 p.m. Through Oct. 20.
