Headdesk. I actually need to go back and watch Blade Runner again because I think I have ther versions mixed up (I think I meant the director's cut which adds the critical lines you mention)- and I like the hints Harrison Ford's character may not be human.

Phillip K Dick's stories are definitely interesting (and crazy at times). Unfortunately Hollywood has not done well with them (Total Recall misses the point and Paycheck could have been stronger).
