Danny Boyle has directed movies in a broad range of genres, from the edgy “Trainspotting” to the award-winning “Slumdog Millionaire”  and “127 Hours” to the charming “Millions” and the trippy “Trance.”  Moviemaker has his 15 “Golden Rules for Moviemaking,” worth reading for its applicability to many different fields of endeavor.  I especially like what he says about being true to yourself but not being afraid to explore other cultures or absorb feedback — and about the daunting challenge of following a big hit.
