Carrie arrives on DVD and Blu-ray today, featuring over an hour's-worth of bonus content, including a "shocking alternate ending." What's that ending? Well, my copy arrived today and before I could crack it open, I had to see if this other conclusion was on the web. Guess what? It was. Ah, you've done me good, Internet.
Obviously, this is all spoiler territory from here on out.
The ending finds Gabriella Wilde's Sue Snell in the hospital, very much pregnant and about to give birth. The minute-and-a-half alternate scene drags on, depicting a painful baby deliver until…well, just watch. It's got a Humanoids from the Deep vibe.
I kind of prefer this one to the theatrical ending. It's just batshit crazy enough for me.
