Confirmed by the person or someone close to them: full chart shown, including houses and the rising sign.
Note on this rating: Birth date 1959-03-15 from Wikidata Q318712 (day precision) and the English Wikipedia article, which agree. Birth city Riihimäki, Finland from Wikidata P19. Birth time unknown, so Rodden X and the time is an estimate.
This page compares the nine bodies a birth date alone can place, Sun through Pluto, and lists the Chiron and lunar node contacts alongside them. The Moon is drawn as the span it could have moved through and is scored in nothing here; the ascendant axis and the house ring are left out by design, not by omission, so nothing on this page is scored against a birth time it cannot trust.
The overlap
Where the two charts touch
Laura Dern’s Chiron and Renny Harlin’s Sun are 0.29 degrees from an exact conjunction.
Both birth times are exact, so the Moon joins Sun through Pluto on both axes, and every contact also carries the house it falls in on the other person’s chart. The ascendant axis and the house ring are drawn.

23 of the 34 contacts fall between Sun and Pluto, and all 23 are in the grid. A boxed cell is within one degree. The other 11 contacts involve Chiron and the lunar nodes and are listed below, 3 of them in the tight layer.
A cell is a plain glyph. The aspect it names is a Codex Link in the sentences above.
Laura Dern inner ring, Renny Harlin outer ring, with the contacts inside one degree drawn. 5 of them are between Sun and Pluto; the rest involve bodies that are not on either ring.

8 of 34The contacts closest to exact, whichever bodies they involve. 3 of these are Chiron or lunar node contacts, so they are named here and are not in the grid above. Tightest first, which is the only order that holds for every pair.

Shared generation
3 of 34Jupiter through Pluto on both sides. Born 8 years apart, these two have their outer planets in nearly the same degrees, so anyone born near them shares most of this group. Listed because it is real, kept apart because it says little about the pair.

Trines and sextiles are soft, squares, oppositions and quincunxes hard. A conjunction depends on which two bodies meet, so it carries no tone here.
Why they click
Every contact here runs between Venus and Mars, or from a Sun into one of them. Sun sextile Venus at 1.78 is the tightest and the friendliest. Attraction scores 85, well clear of everything else in this chart, built on Venus square Mars and Mars opposite Venus working the same pairing from both directions.
Why they clash
Identity, communication, friction and values all sit at the floor. There is no Sun-to-Sun contact, no Mercury contact of any kind, and nothing linking what either person thinks matters. Four aspects, all in one register. On this scale the chart describes chemistry with no scaffolding around it.
What each system says
Twelve systems, two people
This is what comparing two charts system by system looks like: the same birth data on both sides, read against each other one system at a time.
The Suns are 32.8° apart, outside orb of any aspect, which is why identity reads as an empty channel above.
A second tradition
Guna Milan (Ashtakoot)
Guna Milan is the compatibility method used in Vedic matchmaking, traditionally consulted before an arranged marriage. It scores eight factors between two Moon placements on a 36-point scale, shown here as what this one tradition reads: not a verdict, and not averaged with the Western reading above, which may disagree.
The reading
30.5 of 36
Two things stated plainly rather than left silent: Varna and Vashya use a directional rule from traditional bride/groom roles, applied here in the order the two people are listed on this page rather than assigning either role. Bhakoot dosha's most common cancellation, matching rashi lords, is applied; Nadi dosha carries no cancellation here, though same-nakshatra-different-pada is sometimes cited elsewhere as easing it. Mangal (Kuja) dosha is a separate check and isn't part of this reading.
Frequently asked
Are Laura Dern and Renny Harlin astrologically compatible?
Their charts make 34 cross-aspects, the tightest at 0.29° and 3.59°. Astrology does not score a relationship out of a hundred, and the number on this page counts how much contact two charts make, not how well two people do.
What does trine mean between two charts?
A trine puts two placements in easy relation, a flow that takes little effort to access. Laura Dern and Renny Harlin have 8 trine contacts between them, more than any other type.
