10 Star Wars Secrets Everyone Knows But You
7. Han Solo's "I Know" Was Completely Improvised In The Moment
For the longest time it was largely believed that, being the loveable maverick fans knew him to be, Harrison Ford had decided to cheekily go off-script in the heat of the moment with Han Solo's utterance to his beloved Princess Leia of "I know" on the back of her declaration of love towards the smuggler.
In actual fact, though, said line, while not in the original script, wasn't actually entirely improvised on the fly by Ford there and then. Thanks to recordings from the set of The Empire Strikes Back now being made available to dive into and Vulture later providing confirmation on the matter, it was later revealed that the actor actually discussed replacing the previously planned response of "...just remember that, 'cause I'll be back," with director Irvin Kershner on set.
Then, after some typical Ford persuasion tactics that consisted of him feeling "I know" better fit the sequence and Solo in general, Kershner eventually granted Ford this request and an instantly iconic one-liner was emphatically born... just with a little prior planning first.
