Dramas such as 'Vikings', 'Peaky Blinders' and 'The Tudors' are known for their pitched battles and gory bloodshed.
But now the long-running legal battle between a German film company and two well-known Irish film producers has been resolved.
Berlin-based W2 Filmproduktion Vertriebs GmbH sued producers Morgan O'Sullivan and James Flynn who allegedly diverted the funds out of Octagon Films Ltd, a company in which they'd all been shareholders.
The German company claimed between €40m and €50m was diverted out of the company, to either the defendants or corporate entities controlled by them.
Both the defendants, who are directors in Octagon, strongly denied the allegations.
The action, which first came before the court in 2016, returned before Ms Justice Teresa Pilkington yesterday when she was informed that the case had been resolved after mediation.
Edward Farrelly SC, for the German company, said that as part of the settlement the defendants had agreed to buy his client's shares in Octagon.
Under the agreement, the shares in the film production company are to be bought by certain dates. Counsel for the two producers Bernard Dunleavy SC said his side was consenting to the settlement.
Under the agreement, counsel said his clients would retain control over Octagon, and the entire proceedings could now be struck out on consent.
No other details of the settlement, which are understood to be confidential, were revealed in court.
Ms Justice Pilkington welcomed the resolution of what was "a very difficult and complex matter".
It was claimed Octagon was involved in productions such as 'Vikings', 'The Tudors', 'Penny Dreadful', 'Love Hate', and many more.
W2 had sued the producers on behalf of Octagon by way of a derivative action - which is a claim brought by a shareholder on behalf of a corporation against another party.
Mr O'Sullivan, of Ardmore Park, Bray, Co Wicklow, and Mr Flynn, of Ballyedmonduff Road, Stepaside, Dublin, who between them own 51pc of Octagon's shares, denied they traded as Octagon or had used the company's name and reputation. They claimed Octagon was a separate entity to work-for-hire film production services with which they had been associated.
