Nolan: romantic comedies are the hardest genre to make

Christopher Nolan told Jimmy Fallon's talk show that romantic comedies are, in his view, the most difficult film genre to make. He explained that making audiences laugh is one of the hardest challenges in filmmaking — unlike other genres, where an unexpected lack of reaction can be brushed off. Nolan has previously expressed interest in making a horror film, but ruled out a rom-com.
