All movies have their own unique selling proposition because they’re all tailored for different people with different tastes. Some people have no interest in seeing the Avengers, but that is why advertising is so important! Because it is possible to sway those people on the fence with strategic marketing efforts!
Movies have a huge advantage when it comes to advertising because they don’t have to worry about indirectly promoting a substitute (similar product). If you were to see a commercial for shampoo or lotion, but it told you it wasn’t coming out for a couple of months, what would you do? If you’re like %99 of people, when you go out to buy shampoo or lotion, you’re not going to go home empty handed because the new brand wasn’t there. You may recall the brand and even the commercial, but in the end you buy what’s available. And movies have the ability, unlike many other products, to build anticipation before their release! This is good news for the people sitting in the Box Office. IF YOU MAKE MOVIES, THEY WILL WATCH THEM.
