Having not seen Redgrave, I can only attest to Jessica Lange's performance, which I found thrilling. This almost phenomenal revival of an almost perfect play (I stand by my opinion that the deathly fourth act is far too long) really highlighted her. Only once did I see Jessica instead of Mary. Immediately after seeing the production, I wrote this of her performance:
"But most of these quibbles can be excused for the ferocity of Jessica Lange's performance. Every time she was on stage, the room was filled with life. Her slow descent was gripping and her conflicting delusions and bitter self acceptance were a thrill to experience. Act III gave her the most room to fully showcase her prowess, her voice high and lilting one moment, and low and rumbling the next. Her many monologues were phenomenal and her scenes with Byrne were thrilling. That was a taste at what the production could have been: two incredible actors fully embodying their characters. The final scene of the play was a bit of a let down, as her monologue was stretched a bit thin by how slow she spoke, and the voice she used when in memory was very hard to hear up in the mezzanine. But the last line gave me chills, and I can't forget her face as the lights faded out.
