Netflix made a splash this year by creating its own TV shows and delivering them over the Web. Now it’s toying with the same idea for movies. This summer, the company announced that it in addition to TV shows like “Orange Is the New Black,” it would start spending money on modest movies — documentaries and stand-up comedy specials — which would debut on the service. Now Netflix is floating the idea that it will foot the bill for a “big” movie, which would appear in theaters and on Netflix at the same time. During the company’s earnings call last week, content boss Ted Sarandos said the company was interested in breaking into movies, and that investors should “keep [their] mind wide open to what those films would be and what they would look like.”
