Reply #13: Joanna Cassidy came back to reshoot her chase scene

[Frank Cannon]

I guess it was pretty obvious in the original that it was a double running away from Deckard just before he "retires" her. Scott shot new footage with Joanna Cassidy (who still looks great, by the way), and that footage is now in the film.

Also, I heard that the dove at the end flies off into the night sky, not a blue daytime sky.

Those are two tweaks I heard about.
