Themes and Characteristics

Male friendship
A recurring theme in Entourage is the strength of male camaraderie and its importance over work. Series creator Doug Ellin stated, "Entourage works because it's about male friendship. The Hollywood setting is entertaining but it's really about the relationship between these guys". He later added that, "Ultimately, the show's theme is friendship and family. The characters may have the bling, but they're grounded guys who look out for each other. That's the backbone of the show. If it was just about fantasy lifestyles, it wouldn't be relatable".
This view was supported by Jeremy Piven, who plays the talent agent Ari: "If it was just a show about wish fulfillment and guys getting fucked because their best friend was famous, it wouldn't be that interesting."
To strengthen the bond between the actors, only actors with ties to New York were chosen.

Hollywood lifestyle
Episodes of Entourage focus, beside the friendship between the four main characters, on their lifestyle in Hollywood. Specifically, the various parties and movie premieres they visit, as well as the advantages and disadvantages of being, or being connected to, a star on a person's social status. To lend credence to the show's situations and locations, most episodes of Entourage feature at least one celebrity guest star.
