And what about battle? Maybe not a big epic Hollywood style, but I'm sure that a new adaption will have their own take on the battle scenes. A battle scene works better for stories like LWW, PC, HHB, and LB, than it does for VDT, SC, MN, and LB.
It's most likely that the battle scene in LWW won't be focused on as much as it was in the Walden. Though just about every screen adaption of LWW actually shows the White Witch turning people into stone and Edmund breaking the wand. Maybe a way to do the battle is do it kind of like what the animated did, where while Aslan and the girls are on their way to the White Witch's castle, cut every now and then to the battle. It could help build up the tension, "Can Aslan free the statues in time?" Another possibility is have the battle in fog and we hear noise in the background. Then when Edmund breaks the wand, the fog or mist goes away.
I'm sure that a screen adaption of PC will want to include the duel between Miraz and Peter. They might cut back and forth between the duel and Second Battle of Beruna and Aslan freeing the school children and the romp with Bacchus and Silenus.
The Battle of Stable Hill will be a hard one to pull off. The dwarfs shooting the horses and the Calormenes, and a new set of Calormenes using spears. This is perhaps the most detailed battle we get in the series.
