This twosome thankfully didn’t appear in the same version of the Robin Hood movies, but they’re equally worthy of inclusion. Kevin Costner laid down the original marker back in 1991 in Robin Hood: Prince of Thieves by effectively discarding his early efforts to blend in with the Nottinghamshire twang and sounds more like the American he is. But perhaps he made the smarter (if lazier) choice: for Russell Crowe truly raises the stakes by managing to make Robin Hood an unwieldy mixture of Irish-Australian-Yorkshire man. Infamously, he walked out of a BBC interview (you can hear it yourself by listening to this clip) when it was suggested that the star of Robin Hood sounded Irish. “You’ve seriously got dead ears if you think that’s an Irish accent,” Crowe ominously told broadcaster Mark Lawson shortly before supposedly waving his cigarette and cutting the conversation short by walking out. Some cinemagoers would have had a similar urge.
