This was shown in theaters a few years ago. Was curious if this is available online or dvd for purchase or otherwise?
it's on that British digital theater website I believe (digitaltheatre.com)
Actually it's not. It never became a permanent part of their catalog. I purchased it the day it was released and since it's not in the catalog I can still watch it but only on a computer or laptop, 'or via the Digital Theatre app anymore like I can for Into The Woods.
