A tease here and a hint there
The phrase is a reference to the selection of movie snippets, better known as movie trailers, which film producers unleash onto the public prior to a film's general release.
A short film trailer (usually less than 2 minutes in length) is sometimes called a teaser, it acts as a tantalising bait by drawing the public's attention with shots taken from the story, and promises the movie will be greater and ‘tastier’ than imagined.
Oxford Dictionaries tells us that a teaser is
3. A short introductory advertisement for a product that stimulates interest by remaining cryptic:
The noun teaser is derived from the noun and verb tease, Etymonline suggests that the former emerged in the mid-1930s. By comparison, a (movie) tease provides the general public with enough glimpses, in order to whet their curiosity and increment their desire to see more. In this way, it is similar to the second meaning cited in Cambridge Dictionaries.
This possibly explains the passage from a short trailer to teaser, and then tease. In fact, we have to look at its 8th definition in Webster's College Dictionary to find any specific reference to the world of entertainment.
8. Also, teaser. a short scene or highlight shown at the beginning of a film or television show to engage the audience's attention.
In addition, a hint in this context, could be a suitable synonym for tease. Hints in trailers can suggest, and allude to the movie's most exciting scenes. They can provide the audience an anticipatory whiff, or peek into the future that strongly suggest the movie is worth seeing.
(OD) 1. A slight or indirect indication or suggestion:
- Hint (noun) an indirect, covert, or helpful suggestion; clue
To hint is to convey an idea covertly or indirectly, but intelligibly: to hint that one would like a certain present; to hint that bits of gossip might be true.
However, due to the length of a movie tease(r), a hint can also mean a small amount, a sample, or a taster.
The phrase “a tease here, a hint there”, or its slightly more popular variant, “a hint here, tease there” is relatively uncommon, but not so the fixed binomial expression, “here and there”, whose specific order is well-established in the English language.
14. here and there,
in this place and in that; at various times or places:
