"Boogie Nights" is an entire movie about the porn industry, but surprisingly, it also has a pretty compelling plot. The film follows porn star Eddie Adams's (Mark Wahlberg) rise to fame during the "Golden Age of Porn" in the '70s. He assumes the persona of Dirk Diggler and cosies up to fellow porn stars Amber Waves (Julianne Moore), Rollergirl (Heather Graham), and Reed Rothchild (John C. Reilly). But the height of fame and fortune can't last forever, and Eddie eventually falls from grace. With "Boogie Nights," you get sex, drugs, and rock 'n' roll. And more sex. Lots of sex.
