The actor, who stars in this week's vampire film Daybreakers, told the Los Angeles Times that only movies about important subjects should have lengthy running times.
"I don't know what has happened to movies, but lately every movie is at least 20 minutes too long," Hawke commented. "It used to be that if you were three hours long it was because it was epic - a movie about Gandhi; something with very important subject matters.
"Now, it doesn't matter what you're making a movie about; everyone thinks their movie is so brilliant that it has to be three hours long. Not to be critical but... well, we all know which movies those are."
