In what ways were the movies, for all their glamour, similar to the automobile industry as developed by henry ford

The correct answer to this open question is the following.

The ways in which movies, for all their glamour, were similar to the automobile industry as developed by Henry Ford, was in the consumerism behavior of those years.

Let's have in mind that there was a name for that consumerism period called "the Roaring 1920s," in which people had money and spend most of it on new cars, houses, furniture, and other things. The purchase of things was made mostly on credit. The movie industry became part of that glamour for the press cover it had and the creation of stars that became so popular.

In economics, a free market is a system in which the prices for goods and services are self-regulated by the open market and by consumers. In a free market, the laws and forces of supply and demand are free from any intervention by a government or other authority and from all forms of economic privilege, monopolies and artificial scarcities. Proponents of the concept of free market contrast it with a regulated market in which a government intervenes in supply and demand through various methods such as tariffs used to restrict trade and to protect the local economy. In an idealized free-market economy, prices for goods and services are set freely by the forces of supply and demand and are allowed to reach their point of equilibrium without intervention by government policy.
