Steven Spielberg has predicted that the movie industry is in danger of "meltdown".
The Lincoln director said an "implosion" was inevitable, whereby a few 250 million dollar movies flop and change the industry. He suggested that cinema-goers could see price variances for tickets, according to The Hollywood Reporter.
During his speech at the opening of the University of Southern California's new Interactive Media Building, Spielberg also revealed that his Oscar-winning film Lincoln was nearly made for a TV network because of problems getting it into cinemas.
He said some ideas from young filmmakers "are too fringe-y for the movies", and continued: "That's the big danger, and there's eventually going to be an implosion - or a big meltdown. There's going to be an implosion where three or four or maybe even a half-dozen mega-budget movies are going to go crashing into the ground, and that's going to change the paradigm."
Spielberg said then "you're gonna have to pay 25 dollars for the next Iron Man, you're probably only going to have to pay seven dollars to see Lincoln".
He said that Lincoln, which starred Daniel Day-Lewis, came "this close" to being an HBO TV movie instead of a theatrical release.
Star Wars creator George Lucas also took part in the event and warned that the industry could see big changes, with fewer movies released and higher ticket prices.
The filmmaker said cable television was "much more adventurous" than film these days and that "the pathway to get into theatres is really getting smaller and smaller".
"I think eventually the Lincolns will go away and they're going to be on television," he said.
Lucas also referred to the movie Red Tails, which he executive produced. He went on: "We're talking Lincoln and Red Tails - we barely got them into theatres. You're talking about Steven Spielberg and George Lucas can't get their movie into a theatre."
