We in the US don't have to miss out. Fathom Events (the same company that handled the in-theater presentations of "The Day of the Doctor" and "Deep Breath"/"Dark Water", as well as the David Tennant Celebration back in 2014) will be showing the "Shakespeare Live!" in the US, a month late (May 23) and called "The Shakespeare Show" (because apparently Americans need a cheesy title to make us attend this kind of thing).
