Though Nicholas Pileggi's source book, Wise Guy, gave this screenplay both its voice-over and its final conclusion, the screenplay to GoodFellas is an essential addition to any screenplay library. If not for the fact that Pileggi and Martin Scorsese have pulled off the mammoth task of interpreting the detailed-packed, wide-scoped vision of the book into cinema-speak, then for the writing itself. GoodFellas is a screenplay that can be read as entertainment -- fast-paced, crisp, clear, and exciting. The published version of this script is mostly in master-scene form, giving only the most evocative details, beautifully paced. This is one of the crowning entries in Faber and Faber's superb screenplay series, ranking right up there along Paul Schrader's Taxi Driver and Odets/Lehmann's for Sweet Smell of Success. To any upstart screenwriter or serious student of film, this series is invaluable.
