Danny Boyle likes not knowing how to make a film before he starts shooting.

The 'Trance' director has revealed that he doesn't over-prepare for his movies and prepares to wait for inspiration to strike and figure things out as he goes along while filming.

He told BANG Showbiz: ''I like not knowing quite how to do a film. I like trying to discover it as you go along, rather than feeling like you know how do to do it or, 'It will be like this.' It becomes a discovery as you go along as you make the film.''

The veteran director has enjoyed a varied career with films ranging from feel-good dramas such as 'Slumdog Millionaire' to darker psychological thrillers like his latest movie, but he insists he doesn't specifically pick projects that are different to his previous movies.

He explained: ''You don't do that self consciously. You try and respond organically to stories you want to tell, or you find in a script or a book. Obviously, the fact that they're slightly different to the ones you've done before is part of that attraction. You don't try to think self consciously about deliberately doing something different, though.''

'Trance' is out now.
