Funny you should choose the scene on the bed as your favorite dialogue, for Stallone, who wrote the movie, practically "stole" the scene from the claws of the producers!
If I remember the anecdote well (tell me if I'm wrong), one of the executive producers had just come on set and vehemently orderes to shut all cameras and lights to cut off the budget diarrhea.
Stallone asked a cameraman for a quicky and they shot this brilliant scene in one desperate shot...
(And I believe a lot of screenwriters would love to be able to actually rebel against the guillotine in such panache ! )
