Ed Claudio, founder of Actor’s Theatre, celebrates his 20th anniversary in Sacramento by taking a fatherly role in three one-act plays: David Mamet’s Dark Pony and Reunion, and A Stone Carver by William Mastrosimone. He’s ably assisted by a number of his students. Although the Mastrosimone piece was still a little rough on opening night, in Claudio’s masterful hands, it will have its sea legs soon. Th, F, Sa 8pm, Su 2pm. Through 10/4. $13-$15. Actor’s Theatre at the Three Penny Theatre in the California Stage Complex, 1721 25th Street; (916) 456-7066; www.actinsac.com.
