“Among the 600 professionals annually employed by OSF are the 100 actors who make up its repertory acting company — the largest repertory troupe in the country, ranging from new faces to actors who are 20-year veterans. (Among its alumni: Denis Arndt, nominated for a Tony this year for “Heisenberg.”) With diversity a major concern for Broadway and the theater industry at large, 61% of this year’s OSF ensemble are actors of color.”
