Actor who stripped down: Heather Graham
Why they’re fully nude: When you’re a porn star, it’s part of the job description.
It only makes sense that a film about the porn industry would feature full-body flashes. It just seems odd that Amber Waves (played by regularly nude Julianne Moore) would be the one to keep (most of) her clothes on.
Such modesty does not apply to Rollergirl (Heather Graham), who happily sheds what appears to be a onesie in order to confirm that Dirk Diggler (Mark Wahlberg) has got what it takes to make it in the movies. He certainly does. Though it doesn’t make an appearance until the final scene, Diggler’s “giant cock” (Amber’s words, not ours) is the real star of Paul Thomas Anderson’s epic ode to smut.
