Plot hole: The Bishop in the film is performing the duties you would expect of someone in his position (giving mass, hearing confessions, performing weddings etc.) He has his own private chambers in the cathedral, refers to Robin as 'the boy I knew' and talks about hearing his Father's confession four months earlier; so he's been around for a while. The problem is the credits refer to him as the 'Bishop of Hereford'. No explanation is ever given for why the Bishop of a city 100 miles away is living and working in Nottingham rather than looking after his own diocese; or why the Bishop of Nottingham isn't around to look after his. (The Bishop of Hereford was an enemy of Robin Hood in the original ballads, and it's likely the filmmakers just gave that name to the Bishop in the film due to its familiarity, without thinking about the plot hole this creates).
Factual error: Robin and Azeem land at the white cliffs and Robin says something like, 'Tonight we will dine with my father'. Those white cliffs are the Seven Sisters in East Sussex, about 200 miles from Nottingham. It would probably take about two weeks to walk it. They also reach Hadrian's Wall in the next scene, which is 200 miles further north than Nottingham.
Trivia: There is a close relation between Sean Connery and Robin Hood. Connery played Robin Hood in the movie "Robin and Marian" in 1976. His son, Jason Connery, played this same character in "Robin of Sherwood," the TV series, in the eighties. And, finally, he had a small part in "Robin Hood: Prince of Thieves" as King Richard.
Question: Who exactly are the masked cult of which the Sheriff is a member, shown at the beginning when he unmasks and demands that Robin's father join them or die? If memory serves, the cult and the Sheriff's affiliation with them isn't referenced again at any point in the film. I know the Sheriff and the Witch are dark magic practitioners, but that was suggested to be a private thing between them in the bowels of the castle.
Answer: They were obviously some satanic cult as they accused Robin's father of being a devil worshipper. He was asked to join them.
Chosen answer: The masked men weren't part of a cult, they were the Sheriff's soldiers, the same ones that Robin meets when he first returns home. They are just in hoods and masks to appear intimidating while trying to kill the noblemen, like Locksley.
