Every year, the Arvada Center's Black Box Theater repertory company selects a group of top-flight actors for the season. These performers get several weeks of paid work, challenging roles in a never-predictable roster of plays that range from classics to surprising premieres, and a chance to work with great directors and sophisticated tech people. As a result, artistic director Lynne Collins tends to have her pick of talent. While the performer lineup changes year to year, the standard is always high.
