Grandage noted that the Broadway industry was "much more commercially minded," adding that it is "effectively, built around the Tony Awards," with producers and press agents strategically planning for the June awards ceremony.
"The entire system is built around, 'Here's our work, now tell us how we did through a prize,'" he added.
All three of Grandage's Tony-nominated productions (including his win for John Logan's Red) opened within the spring awards crunch in New York.
As far as a Broadway transfer for Kidman's Photograph 51, the Anna Ziegler drama about Rosalind Franklin – the woman who cracked DNA – Grandage said that it was "still up in the air" and that discussions were not underway. Kidman currently has another film project lined up following the London run of the play. "It wouldn't be happening until much later," Grandage said.
