Potioncat:
In the book, it seems pretty clear that Snape gave Umbridge fake serum. 
When he said there wasn't any more, he also adds that it only takes a 
few drops, surely she hadn't used it all? Showing that she doesn't know 
much about the potion. 

In the movie, he gave her the real thing. His comment is that she used 
the last of it on Cho. So that changes Snape's behavior completely. Of 
course, it covers for the fact that Movie!Snape poured an entire vial 
of it down Barty's throat.
