His portrayal of Eliot in Tusk Tusk received praise from a broad spectrum of theatre critics. Michael Billington from The Guardian called him an "astonishing actor". Robert Tanitch from Morning Star praised both his and co-star Bel Powley's "impressive performances" and predicted that "Tusk Tusk should, all things being equal, play to full houses because of them". Matt Wolf, writing for The New York Times, was also very complimentary about the pair, concluding: "... these newfound talents inhabit every mercurial point on a spectrum that makes them one another's protectors and their destroyers, enemies and allies. Will you be more shaken by Ms. Powley ..., or Mr. Regbo, whose face is chillingly capable of shutting down? It's difficult to say, though one thing is clear: Tusk Tusk is beyond tears in a production beyond praise."
