Actor's Choice opened Suzan-Lori Parks' Pulitzer Prize-winning drama "Topdog/Underdog" Thursday in the Henry Clay Theatre. Directed by Kathi E.B. Ellis, this tense, finely-acted two-hander explores the relationship between two adult brothers, Lincoln and Booth, as they struggle with a legacy of abandonment by their parents, masculine identity, racism and the lure of a life of crime.
