The Irish theatre director Tomás MacAnna was artistic director of the Abbey Theatre on three occasions and proved to be a major supporter of O’Casey’s work. This chapter traces MacAnna’s interactions with O’Casey’s writings, pointing to a number of key stagings and explaining how MacAnna wanted Ireland to follow Germany’s example in using O’Casey’s scripts as part of a developing culture of theatrical experimentalism. This chapter demonstrates how, after O’Casey’s death, MacAnna directed a remarkable number of unfamiliar O’Casey works at the Abbey Theatre between the late 1960s and the mid-1980s, although the chapter shows that the reception of these works was often lukewarm or hostile.
