In watching Les Mis bootlegs from the '90s, I've noticed a recurring difference in how one line is delivered in the replica productions vs. foreign non-replica productions.
The line in question is Combeferre's "Though we may not all survive here, there are things that never die," after Javert's capture, which was cut when the show was shortened by 14 minutes in 2001.
In the non-replica productions, Combeferre tends to deliver that line to Javert, as a rebuttal to Javert's "Death to each and every traitor! I renounce your people's court!" He seems to be saying "Yes, we may die, but our values are righteous and will live on, which is more than you can say for yourself, spy!"
But in the replica productions, he delivers the line to his friends as he lowers the guns they've aimed at Javert, to remind them of their values and dissuade them from shooting Javert on the spot like assassins. This is especially true in the 10th anniversary's more chaotic re-staging of the scene, where Courfeyrac incites a near-mutiny to shoot Javert until Combeferre intervenes.
Both of those deliveries are valid and I have no idea which one the authors originally intended. But Trevor Nunn interpreted it one way, while the foreign non-replica directors chose the other.
