Igor holding Sue in Egg Corridor disappears on screen

[Lulink13]

I have an idea to fix all or most of the character spawning / despawning on screen during cutscenes:
put black bands on screen to get the 4/3 resolution during cutscenes. That would look cool too, like the letterbox effect in other games even though the letterbox is supposed to be used on the top and bottom of the screen. The only problem with that would be the HUD: either hide it or make sure it's always fully covered by the black bands.
