I don't remember if this got discussed, but just ran across it.
Among other things, there's the expected explanation for one of the stupidest scenes in the movie as edited:
However, the biggest find is the Lindleloff script.... Haven't read it yet, but now we can see just what he did and didn't contribute....Spaihts tries to explain away the idiocy of the scientists Milburn (Rafe Spall) and Fifield (Sean Harris), saying it was more due to editing, since they cut an earlier scene of Milburn becoming ecstatic over the discovery of a harmless alien life form: “It really showed how excited Milburn was by experiencing any extra-terrestrial, sophisticated life. That sort of explains why he’s acting like a complete utter moron here. The last thing you do when you see a snake in the wild is get your face really close to it and start smiling and extending your hand like you wanna pet it.”
The earlier Spaihts script is here:
