Yeah, I know Trek has a niche audience, but given how many poor sequels outgross their predecessors and Star Trek II's positive reputation, I remember being surprised after reading the box-office totals for the old Trek films.
TMP got a lot of the general audience intrigued about a "reunion movie", but on the scale of "2001". The first "Star Wars" movie ran for over fourteen months in the cinemas, and suddenly here was yet another SF blockbuster. Here Down Under, TMP ran in city cinemas for over six months, then began a tour of suburbs and country towns.
By the time ST II came along, films were opening in more cinemas, but for shorter runs.
Some have said that if TWOK had been considered a failure back in 1982 we wouldn't have gotten TNG.
It was the blockbuster business of
ST IV that caused Paramount to seek a new weekly ST series.

that resulted in rather limited budgets for the subsequent movies.
Sure. Why spend more, when less equals
more reliable profit ratios?
