Film studios pay to put trailers in front of films not by their production companies. Not a secret - happens all the time.
Still, because the general public doesn't know RENT, I'd imagine HOUSE OF WAX is what will happen. It depends on the marketing strategy.
Another possibility is that it debuts on an entertainment news program, such as ENTERTAINMENT TONIGHT or EXTRA. This also happens a lot with teasers, and even full trailers. Happened with the 2003 film PETER PAN.
If it debuts on an entertainment news TV program, this means it'll be online within 3 days after it airs, and 2 weeks later it'll be in theatres.
"The Spectacle has, indeed, an emotional attraction of its own, but, of all the parts, it is the least artistic, and connected least with the art of poetry. For the power of Tragedy, we may be sure, is felt even apart from representation and actors. Besides, the production of spectacular effects depends more on the art of the stage machinist than on that of the poet."
