Movies typically have ONE main trailer...
Since when? Nowadays it's common, especially blockbusters, to have a Teaser, Main trailer 1, Main trailer 2 closer to release, then snippets/short TV spots/etc.
Just went to the Universal YouTube page
Twisters: Official Trailer (10 months ago), Official Trailer 2 (7 months ago)
Wicked: Official Trailer (7 months ago), Official Trailer 2 (3 months ago)
Speak No Evil: Official Trailer (8 months ago), Official Trailer 2 (4 months ago)
Oppenheimer: Official Trailer, New Trailer
