Within that setting, we follow Dirk and his adopted family, which includes the young starlet Roller Girl (Heather Graham) and the house mother-esque Amber Waves (Julianne Moore), all of whom work for adult film director and pseudo-father figure Jack Horner (Burt Reynolds).Īs the saying goes, what goes up, must come down. Set in the late '70s, 'Boogie Nights' charts the last days of an era, right before videotape, which is much cheaper to shoot on than film, took over as the industry's dominant format. In this case, that kingpin is Dirk Diggler (Mark Wahlberg), a young man with a special 'talent' who rises to the top of the porn industry in Los Angeles' San Fernando Valley.
