Are you sure you saw the play? Reiner didn't play BlankenHORN. Reiner replaced himself with John C. Reilly shortly before the event, and just directed. Maybe you just based your review on an outdated press release
If the reviewer went to the Beverly Hills Saban Theatre, he was in the wrong place. "8" was performed at the Wilshire Ebell in Los Angeles.
Good golly, Mr. Morris, get your information correct before you write a review, which you probably saw on You Tube, not even in the theater.
To both corrections: Our estimable critic was at the right theater. The Saban was a copy editing error, for which I take full responsibility. The Reiner/Reilly substitution was a last-minute thing and not announced in the program or the theater before the performance. We apologize for the error. - Lisa Horowitz, copy chief
