They made a longer version of TMP?
It's the VHS version. Every video copy I've ever seen has fine print underneath the title that reads "Special Longer Version".
Interestingly enough, the longer version has some good interaction between the characters --particularly, scenes in which Spock explains V'Ger's side to Kirk.
That said, the Director's Edition is FAR superior to the older ones. Most of the clutter is either cut or tweaked to fit better.
My compliments to Bob Wise --even if he did
refuse to give Grace makeup....
