For what it’s worth, there are only three performers who came over from London. They are Hiran, who does an amazing job as Pi, as well as Fred Davis and Scarlet Wilderink. They all won Olivier awards for their work. HIran for the role of Pi, Davis and Wilderink also one best feature for their roles as puppeteers for Richard Parker.
I know that there are rules for how long a British performer can stay in the US to do a a role. But, considering that Hiran elected to not to do the Boston run, I don’t know if that will allow him to stay longer. The Pi alternate, Adi Dixit played the lead during the Boston run, then came to Broadway as the alternate. Whereas the other two mentioned were with the show in Boston.
