Exorcism: A Play in One Act was recently discovered in 2011. Written and performed in 1920, Eugene O'Neill inexplicably pulled the play out of production and ordered all existing copies to be destroyed. The play was met with mixed reviews.
In the intro by Edward Albee, as a stand alone, it is a not a marked milestone in O'Neill's budding career as a playwright. Albee speculates that O'Neill's dissatisfaction with Exorcism may have to do with his attempt at eradicating this play. However, it is a worthy study as a predecessor to his more well-known works, The Iceman Cometh and Long Day's Journey Into Night.
So, having said that, unless you're a fan or a student of Eugene O'Neill's works, I found that as a reading, it wasn't particularly very good. The end is anti-climatic, and the character interactions were awkward. The play centers around a suicide attempt, but it seems the characters apart from Ned (the character that attempted the suicide), treat the incident with too much glibness. I can understand why Mr O'Neill wanted this work stricken from his distinguished portfolio. However, I'll be sure to read this again if I come around to reading the two critically acclaimed aforementioned works to have some more insight into his work.
