What hit cable TV show is loosely based on Mark Wahlberg's life?

The hit cable TV show loosely based on Mark Wahlberg's life is Entourage.

The HBO comedy-drama premiered in 2004 and follows fictional movie star Vincent Chase as he navigates Hollywood with his longtime friends and older brother, Johnny “Drama” Chase. Wahlberg and producer Stephen Levinson helped inspire the series through Wahlberg's early experiences as an actor surrounded by friends and associates.

The show is not a literal biography. Vincent Chase is a fictional character, and the plots were heavily dramatized. Several characters drew from real people: agent Ari Gold was partly inspired by Wahlberg's real agent, Ari Emanuel, while other characters blended traits from members of Wahlberg's circle. The series ran for eight seasons through 2011 and was followed by a 2015 feature film.

A common mix-up is assuming every storyline mirrors Wahlberg's career. The accurate connection is looser: Entourage borrows the setting, friendships, and atmosphere of his rise in Hollywood rather than recounting his life directly.
