In an answer over on SciFi.StackExchange, I've included a quote from a script on the Internet Movie Script Database, the IMSDb.
I've since used its script for Inglorious Basterds as a source here, too. Twice now.
But how reliable is it? The scripts can be submitted by anyone, so it seems. Are they checked, or just uploaded to the site?
What's to stop me from writing a fictional discarded draft of Star Wars where Leia was Han's sister?
As such, can it be used as a reliable source to base answers on?
