I know in Game of Thrones, the ending, they’re going to shoot multiple versions so that nobody really know what happens.
No doubt Season 8 production will bring plenty of other on-set details, but will Game of Thrones manage to surprise us with its allegedly-bittersweet ending?
Game of Thrones producers knew by Season 7 that filming details would inevitably leak out; to which they posed that certain scenes were staged for exactly that purpose.
Few were necessarily fooled, but Season 8 may go the extra mile to film several endings to the Song of Ice and Fire saga.
