Hasbro attempts a backstab on Warner Brothers, hoping for +8 damage.
To recap, Wizards of the Coast, who acquired the Dungeons and Dragons IP in 1997 by buying the original creators of the game, TSR, had previously licensed the film rights to film-maker Courtney Solomon. Solomon produced a film in 2000 that was a box-office bomb. Solomon retained the film rights, producing two live-action sequels. Meanwhile, Hasbro bought Wizards of the Coast in 1998 and they produced a Dragonlance animated movie in 2008, which didn't step on the existing film rights by avoiding any potential areas of dispute. Earlier this week it was confirmed that Warner Brothers were developing a new big-budget movie with Solomon on board as producer.
Apparently this dispute has come up before and in a binding arbitration process, Solomon's ownership of the film rights was confirmed. Clearly Hasbro didn't accept the 'binding' part of that agreement and it's likely there will be further legal shenanigans before either film project can proceed.
D&D uses a lot of fairly generic fantasy material - elves, dwarves, wizards, clerics, dragons, lightning bolts, fireballs etc - but it does have some specific elements that likely would be affected by the issues, such as drow, beholders and specific spells like Melf's acid arrow. The rumour is that Hasbro has been working to bring some of the more popular D&D worlds and novels to the screen, such as R.A. Salvatore's Drizzt Do'Urden books, but it'd be impossible to do so without treading on areas covered by the existing film deal, which means they wouldn't be able to use them. It remains to be seen how this pans out.
