Four tapes were swiped in August 2006 in Budapest, where the 13-part series was being edited, and the thieves were demanding one million pounds (1.9 million dollars, 1.5 million euros) for their safe return. The production offered a 40,000 pounds reward for the return of the tapes. The Hungarian police found the tapes the next month.
All the main cast went through months of medieval boot camp to prepare for their roles. Yet Lucy Griffiths previously lied about being able to ride a horse well, but once getting the part, she had to learn very quickly indeed.
Lucy Griffiths's cameo in Robin Hood: Something Worth Fighting For: Part 2 (2009) influenced Karen Gillan's cameo in Doctor Who: The Time of the Doctor (2013). Which, the dying Eleventh Doctor hallucinates and Amy Pond appears and walks towards to him and says to him "Raggedy Man. Goodnight!" and The 11th Doctor snaps back into reality. In (#3.13) a dying Robin (Jonas Armstrong) sees Marian (Lucy Griffiths) appear and walking towards him. Marian says to him "The greatest adventure is yet to come". They embrace and in reality, Robin succumbs to the poison and dies.
The series was cancelled after 3 seasons because Jonas Armstrong had decided that he did not want to a fourth season and wanted to leave the series, so he could move on to other projects. The showrunners could not figure out a way to keep the series going without it's main star and since Maid Marian had died at the end of the previous season, it was decided Robin was to die at the end of the third season.
In series 1, Marian criticizes Robin's actions against the Sheriff and his cruelty and injustice. It is later revealed Marian is The Nightwatchman and also fights the Sheriff and is giving the poor food and supplies, which proves that Marian is no better than Robin and is a hypocrite.
