I had no idea that the movies ‘I Am Legend’, ‘Fatal Attraction’ and ‘Clerks’ all had alternate endings that were better than what was shown in Theatres.
For Example, in ‘I Am Legend’ the alternate ending is as follows
It turns out that all the monsters really wanted was Neville's "monster woman" - his test case to find an antidote to the virus. Neville realises this, wakes her up, and the big monster takes her away, leaving Neville unscathed. It dawns on him that his research methods were not fair on his victims. As visual effects supervisor Janek Sirrs puts it, "at that point, Neville's — and the audience's — assumptions about the nature of these creatures are shown to be incorrect. We see that they have actually retained some of their humanity. There is a very important moment between the alpha male and Neville." This is a deeper and more meaningful ending than Neville's self-sacrifice, and would have arguably been a more interesting ending
