Underworld (2003) It was released as an extended cut a while after the theatrical version and len wiseman the director claims it can be considered a directors cut after 20 years.
On the Bluray release of the extended cut now swaps a sequence about the history from the third film which is a prequeal regarding werewolf and Vampire Love affair which was halted and the betrayal there of a new breed of immortal. This was similar but they choose to use the actual prequal instead of the original shoot depicting the back story. Not too naughty but still a change.
