Matthieu Cornillon, understudying for Jonathan Cake, went on stage one night for his Broadway debut. As it happens, some reviewers were in the audience that evening. This is what they had to say:

"Matthieu Cornillon, who subbed for Jonathan Cake at the performance reviewed, is superb as Braham, revealing him to be repulsive even when the insecurities and pretenses of his character are stripped away. I was glad to catch him in his Broadway debut."

"The show’s saving grace is the arrival of two promising young performers. [Anna] Madeley’s nuanced turn as the conflicted Celia bodes well for her future on Broadway, and Matthieu Cornillon shines as an arrogant novelist whose Wildean wit hides an insecure ego. Both are actors to watch."

—Ethan Kanfer, Show Business Weekly

"...a confident performance..."

“…notable performances include…Matthew Sholler and Matthieu Cornillon as Arthur and Lancelet, whose erotic tension is the most believable in the play.”
