Right. But it's always the TV show referencing the movies. Like when DS9 changed over uniforms to match the new Trek movie uniforms from First Contact.
Because the movie is filmed a year before it airs over the course of three or four months, while a TV show is filmed over four days a few months before it airs. So SHIlELD can reference and act as a prequel to Avengers or Captain America since those movies are in the can and just going through final FX and the TV shows can write around them.
Doing the reverse - tying a movie into a TV show - is super hard. When Insurrection was released in December '98 but production work began (sets, FX, etc) at the start of the year. While scripting occurs in mid-1997.
So the movie was written halfway through season 6 of DS9 and aired halfway through season 7. That's a long time to ask the TV show to think ahead.
"Hey, I know you're busy planning the second half of the season... but you could also plan all of next season at the same time so a movie can happen?"
I mentioned "Agents of Shield" because it both foreshadowed AND followed the movies, though it is most certainly the exception.
