Leonardo DiCaprio is wary of signing up to make his directorial debut as he fears his obsessive nature would make him unbearable on set.
The Great Gatsby star has previously revealed he would like to emulate his J Edgar director Clint Eastwood's style of working behind the camera.
"If I did direct, I would try to have the same no-bulls**t approach to it as he and his crew have," he said.
"Seriously, there are no frills on his set. It's a small, tight-knit crew."
However, DiCaprio admits he is filled with reservations about taking control of a movie.
