Boogie Nights (1997)
NOTE: These two commentaries are only available on the 2-disc "Platinum Series" release of Boogie Nights, as well as the Blu-ray release. The original 1-disc DVD release only had the director's commentary track, and not the cast one. The cast commentary is based on the track on the Criterion laserdisc, but is a slightly different edit, with the participation of two additional cast members.
