Bruce Cromer plays Lewis; Barry Mulholland is Freud — both are top-notch performers. Director Michael Evan Haney says of Freud and Lewis, “two giants of the 20th century … with diametrically opposing ideas have a civil, respectful and loving argument.” The winner of several best-play awards in New York City, Freud’s Last Session has generated so much ticket demand that ETC extended its run for a second time through Feb. 16. $38-$42. Tuesday-Sunday. Ensemble Theatre, 1127 Vine St., Over-the-Rhine. 513-421-3555, ensemblecincinnati.org.
