It wouldn't be at all surprising if the film industry began to adopt the style of these minimalist animated movie posters. Although created specifically with the Harry Potter franchise in mind, such a design could be tweaked for other movies as well. Taking the key elements from each of the seven films, the GIFs may be simple, but they capture the particular plots perfectly.
Granted these minimalist animated movie posters could also be considered animated book covers, especially since the seventh wasn't split into two versions. Designed by Jessica Martinez, a digital artist from the Philippines, these minimalist animated movie posters show how relevant the young adult series still is in today's society and how long it was last decades after it was first published.
