Only ET was there as cameras rolled on The Anna Nicole Story during a key scene with actress Agnes Bruckner, in character as the late Playboy model, as she tearfully buried her 20-year-old son, Daniel Wayne Smith. The star's eldest child died tragically of an accidental overdose just months before Smith herself would succumb to a similar fate.

The TV movie, shot this summer, is said to chronicle the true life story of the figure, who grew up in a small Texas town before rising to fame.
