With GLAAD claiming that 20 percent of Americans 18 to 34 years old and 12 percent of those 35–51 identify as LGBTQ, Ellis noted, “If Hollywood wants to remain relevant with these audiences and keep them buying tickets, they must create stories are reflective of the world LGBTQ people and our friends and family know.”
