LOTR is entourage but with Hobbits. You have a DYNAMIC crew of 4 (the titular entourage of Entourage), featuring a leader who drives the group forward and is the center of the plot (Frodo/Vinny CHASE) who has an intense & engaging deep psychosexual relation to his closest friend (Samwise/E), and two people who are connected to the group but never speak with the leader (Merry & Pipin / Turtle and Drama).
In both works they embark from their small hamlet (Hobbiton/Queens) on a grand quest to a great city (Rivendell/Hollywood). When they finally reach it their real quest begins (the destruction of the one ring/Vinny's big Hollywood career). Frodo/Vincent CHASE both have intense mentor mentee relationships with wise elder mentors (Gandalf/Ari) who persuades them into debauchery and their respective quests.
