And let me tell you a little something about Anniversaries (NOT Birthdays). If it wasn't for the 25th Anniversary of Star Trek, Star Trek V would have most likely killed the film franchise. After all, TNG was getting better and TOS just walked away with an embarrassing bomb.
Not so sure. They had a string of four financially successful films. They may have made a picture that was different from The Undiscovered Country
, likely an Academy film, but they would've made one.
