I Am Legend (Blu-ray) - Alternate Ending Version
Reviews of this one on BD were spot on! Transfer is very good and the Dolby TrueHD soundtrack will not disappoint - the BIG explosion when the 'infected' were attacking his home will shake your home.
Finally, I like the alternate ending version better than the theatrical version.
P.S.
When you first insert the disc on your BD player, there is a menu to select which version you want to watch.
