Updated with a pretty good Patsy Kensit film clip, courtesy of “uncle”
=============
Early in her career, when she was six years old, Patsy looked enough like Mia Farrow to play her daughter in the Redford version of The Great Gatsby. About two decades later, she still looked like Mia, so much so that she was cast as Mia Farrow herself in this two-part cable mini-series. To complete the circle, per IMDb, this series actually recreates scenes from the filming of The Great Gatsby!
An actress named Grace Una played Soon-Yi Previn
To my knowledge, this show has never appeared in digital format and is not streaming. A LQ version is on YouTube in multiple parts, but BEWARE. I didn’t watch it, so I don’t know for sure, but it might be a heavily censored version because the online version runs three hours, and IMDb says that the series should run exactly four hours.

Here’s my copy
Thanks!
The quality is pretty decent. Definitely an upgrade.
Ordered a copy from Video Search of Miami back in the day. Uncle’s copy is slightly better than mine. Don’t remember if it was 3 or 4 hrs. Like The Sex Symbol (1974) ~ Connie Stevens, Then Came Bronson ~ Bonnie Bedelia (1969) etc a made for TV U.S. movie w/nudity for Euro release.
Then Came Bronson – good quality-
Kensit was so gorgeous, good sex scenes in Timebomb & Angels and Insects
The young Korean lady looks great too!
