Christopher Nolan needed just 15 minutes to persuade film bosses to let him direct Batman Begins, it has emerged.
The filmmaker's pitch for the 2005 movie was so perfect that Warner Bros were immediately convinced that he was the man for the coveted job, and quickly gave the superhero reboot the green light.
Warner Bros' president of production Greg Silverman said: "The pitch that Chris had was so... it was quick. It was 10 or 15 minutes. But it was so holistic, and it really was Batman Begins."
Former studio president Jeff Robinov explained that Christopher had a very clear vision for the film about the caped crusader.
He said: "Chris came in and said, 'Look, this is what I want to do in the movie. This is what I want to do with it visually. This is where I think the character needs to go. I think it's going to be different than any superhero movie anybody's seen before. And what I really want to do is take that genre and embrace it as a real film genre'."
The Warner Bros bosses were speaking for a segment in the new Ultimate Collector's Edition Blu-Ray set of the Dark Knight trilogy.
Batman Begins - which starred Christian Bale, Michael Caine, Gary Oldman and Morgan Freeman - was both critically and commercially successful, racking up an Oscar nomination and making more than 370 million dollars worldwide.
It also paved for way for the sequels, The Dark Knight in 2008 and The Dark Knight Rises in 2012, and the three films became one of the highest-grossing movie trilogies of all time.
