Acclaimed director Steven Spielberg admits he likes to take on projects that intimidate him, and says he is always nervous when he is on the sets of a new movie.
"Fear is what drives me. Every movie is scary for me and every day I shoot the movie is scary. And I need fear because it drives me to explore things. It keeps me looking for a new variation on constant themes," femalefirst.co.uk quoted Spielberg as saying.
However he admits he did not struggle with working with horses on his new movie "War Horse" which is about a boy whose beloved pet is sold by his father.
