Millions of dollars are spent each year producing and marketing movies. By some schools of thought, whatever the size of the production budget, the marketing budget should equal that. This is definitely true of bigger budget films above the $60 million level. So, a lot of money is spent by Hollywood trying to get people into theaters.
“Television will kill the movies!” That’s what Hollywood was afraid of in the 50s. That’s when wide screen “epic” film formats were developed and movies like Cleopatra and Ben Hur came to represent the movies. The idea was that filmmakers had to come up with something that would clearly draw audiences away from television otherwise no one would ever again leave the comfort of their homes.
