Longtime fans of Entourage expressed uncertainty Thursday following reports that the classic tale of ambition and fraternity will be adapted to the silver screen, with fans conveying their doubts that any film adaptation could possibly do justice to the narrative intricacies and rich characterization of John Updikes acclaimed 1986 novel. Given the sheer density of the original book, I honestly dont see how a two-hour movie could even come close to capturing the complex plotting and immense social impact of Updikes cutting show-business satire, said Entourage enthusiast Walter Landon, echoing the concerns of millions of bibliophiles worldwide who have, over the years, intently read and reread the 1,200-page PEN/Faulkner Awardwinning narrative documenting the shifting fortunes of such timeless literary figures as Vincent Chase, Ari Gold, and Salvatore Assante, known colloquially throughout the novel as Turtle. How will the filmmakers possibly render the pivotal chapter wherein Vince buys E a Maserati? Or the torment experienced by Ari when he is asked to betray his own client? Or the brotherhood evinced in Dramas collaboration with Andrew Dice Clay in the absorbing text-within-a-text Johnnys Bananas? Im sorry, but these are moments that can only really live and breathe on the printed page. At press time, the nations Entourage buffs had reportedly eased their concerns upon learning the films producers had recruited a cast and crew befitting the monumental work, including revered thespians Adrian Grenier and Kevin Dillon.
