Fun Fact: It was Kershner’s idea to have R2 on his tippy toes.
You mean it wasn’t in Kasdan’s script ?
You mean it was improvised ?I really hope Kershner got fired !
It is quite normal to improvise a few things to improve on a great script, it is quite another to throw out the script in favor of complete improvisation. The only one I know of to be able to do that in a dramatic work was Robert Altman. When you try to turn a drama into a comedy improv, and the star, the screenwriter, and the producer don’t like how it is turning out and you refuse to follow the script, it is not going to end well for the director(s).
