A trailer is a wheeled vehicle used to move heavy objects from one location to another. It is also commonly used to transport goods and materials. Trailers are often made of a sturdy material to withstand the weight of the items they will carry. Some trailers are designed to be light. However, not all trailers are created equal. The most popular types are step deck trailers (also known as lowboys or low-beds) and folding trailers. These are usually used to transport agricultural and construction materials.

Several trailer companies operate in Los Angeles, New York and other major cities. Many of these companies specialize in the production of film trailers. Others are involved in other forms of promotional media.

A trailer is a cleverly designed piece of advertising. It is usually composed of scenes from the film it is promoting. It has a three-act structure, often with a notable soundtrack. Depending on the nature of the movie, it may contain a few deleted scenes, a special effects sequence or some other novelty. Its most impressive feature is its ability to tell a story in a compact format.

As a marketing tool, the trailer has evolved from the standard three-act format to a highly polished presentation. Today, trailers are distributed on the Internet and can be viewed in various resolutions. They are also a great way to present a movie to a large audience. In fact, some cinemas even have a “trailer trash” program.

For instance, the Terminator 2: Judgment Day trailer featured an elaborate special effects sequence. While this might not be the most effective means of introducing a film to an audience, it did a good job of showcasing the film’s major points.

One of the most common features of a trailer is a logo or a billing block. The latter is usually displayed on the screen at the beginning of the film. Sometimes the billing block includes a list of the film’s principal cast members and its producer.

Another nifty feature of a trailer is its multi-channel sound mix. These trailers are created from rushes, sometimes using different takes of the same shot. This is especially important because many modern trailers have a limited budget, and therefore are only edited on a tight deadline.

Other features of a trailer are the requisite security chains, tilt-out fenders and automatic brakes. Moreover, most car carriers have a ratchet-operated tire strap. Finally, there are trailers specifically built for moving long distances. Car carriers can cost a little more than tow dollies, but they are generally more stable and can haul more weight.

As a form of advertising, the trailer has proven to be one of the most successful in recent memory. Moviemakers have taken advantage of this opportunity to sell their films to an increasingly diverse demographic. At the same time, many critics have criticized the trailers for being overly misleading, or for displaying more action than is appropriate for the film.
