Star Trek: The Motion Picture Exclusive Deleted Scene | SciFiNow

There are at least four cuts of TMP out there.  My generation remembers the special, longer cut that was shown on ABC and VHS.  This cut has a lot of character moments that were not in the theatrical cut, but also many unfinished shots.  For a long time, that was the only cut we had of TMP.  However, the director's cut has some of the best parts of both cuts.  Even adding a few lost shots. 

One of the bigger deleted scenes not included in any cut was the famous security guard's death.  The scene happened during the probe's entry into the bridge.  The probe kills one of the two guards.  The reason this bit was cut was because it was a continuity issue at the end.  Kirk never mentions this dead guy in his casualty report.  I thought this scene was lost forever.  I guess I was wrong.  It took nearly 40 years to finally see it, though.

Now, only if we could get that deleted memory wall scene...
