Getting comedians sloshed and having them recount the tales of historical figures is a malleable format. Having started out as a web series and then graduated to full broadcast, Will Ferrell and Adam McKay's Drunk History now receives a UK remake. The star wattage isn't as high as its US counterpart (it had Jack Black, Winona Ryder and Dave Grohl), but there are still some redoubtably funny people involved, including Simon Bird, Tom Rosenthal and (playing Oliver Cromwell) Mathew Horne.
