Ring of Fire
Alas, this becomes a failed Site of the Month possibility.
If they had more choices in their archives, I am almost sure it would have been a finalist candidate. As it is, the movies they have selected and produced alternate endings for, I either have not seen or just not cared enough about.
If you read this blog in any regularity, you'll already guess that the two that stand out for me are Star Wars IV: A New Hope and the below clip of The Lord of the Rings. ....though the Borat thing is probably as accurate as you can get. There's 90-120 minutes I'll never get back!
If nothing else, I knew Becky and Jon would enjoy the LOTR one....which I've taken the opportunity to post below. The How It Should Have Ended site made me download some new software to play the movies from their URL. I didn't think you all should have to do that.
Personally, I like Boromir mooning Sauron. ...and the taunt of 'your mother has cataracts'.
So, it's not technically Site of the Month material - but it has its moments.
