It’s Parker’s first big musical, and he gives a warm, moving performance as Professor Higgins.

Nathaniel Parker - exceptional in both roles

Parker as crumpling classics teacher Andrew Crocker-harris is majestic in the role which is both heartbreaking and illuminating as the character develops at the end of the play.

Parker is at his absolute best when he is extracting every last bit of emotion from the script.

He is at his best in the moments where we see the vulnerability behind the bluster, and this is never more apparent than in his awkward awareness that his poetry may not be quite as good as his sycophantic hangers-on insist.

"The cast excel" (The Guardian), led by "superb" (The Stage) Nancy Carroll, the "joy to watch" (The Upcoming) that is Nathaniel Parker and "electrically charismatic" (The Times) Jacob Fortune-Lloyd.

Nathaniel Parker's narration highlights Colfer's action-packed drama, delivering the story's chilling implications of murder and deceit with a breathtaking accuracy of tone.

My gut feeling about Nathaniel was that he could certainly pull Lynley off, so I took comfort in that.
