Randomly stuck on the audio commentary to Empire ages ago and was surprised to hear this spritely, slightly mischievous sounding, ole pro explaining how Vader was able to tear Han's blaster pistol out of his hand using the Force, or as Irvin explained through using some rope and cutting away to show Vader while Irvin actually threw the gun into Prowse's hand.
See, George? It probably cost a whole dollar for the rope. And not a green screen in site
There goes an old pro who was comfortable handling a movie that had so much riding on it.
Engaging commentary to say that least, and I believe he actually listened to Ford's complaints about Han originally saying "I love you, too" to Leia.
He told Harrison to try something different and voila! Movie history
May the Force be with you, Irvin Kershner.
