No birth time on record, so houses and the rising sign are not shown.
Note on this rating: Birth date 1965-08-13 from Wikidata Q3020857 (day precision). The English Wikipedia article gives no birth date, so this is a single-source date. Birth city Sacramento, California from Wikidata P19. Birth time unknown, so Rodden X and the time is an estimate.
This page compares Sun, Mercury, Venus and Mars, the four placements a birth date alone can place. Moon, Ascendant and Midheaven are left out here by design, not by omission, so nothing on this page is scored against a birth time it cannot trust.

The overlap
Two charts, laid over each other
Robert Downey Jr. and Deborah Falconer's Sun, Mercury, Venus and Mars are drawn here, the four placements a birth date alone can place with no birth time required. This is a complete chart of what is known, not a partial chart of what is not.

| Thin line, Mercury to Venus | QUINCUNX 1.61° |

Why they click
Three trines carry this chart. Mercury trine Sun at 0.65 degrees is the tightest and the clearest: one person's way of thinking meeting the other's identity with no resistance at all. Mercury trine Mercury at 3.41 extends that to how the two of them think generally, and Sun trine Sun adds a compatible basic temperament underneath. Communication is the only category that lifts off the floor.
Why they clash
Identity scores below the floor, the lowest reading in this corpus, despite the Sun trine, because at 5.8 degrees that contact is wide and carries little weight. Mercury also takes a quincunx from Venus and an opposition from Mars, so the same planet doing all the useful work is also absorbing all the strain. Attraction, friction and values sit at the floor with no Venus-to-Venus and no Mars-to-Mars contact anywhere.
What each system says
Twelve systems, two people
The Suns are 125.8° apart, close enough to feed the identity category above.
Snake and Snake are in neither the trines nor the clashes.
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.
Guna Milan needs an exact birth time for both people. The Moon changes nakshatra roughly once a day, so an estimated time can place the whole reading in the wrong one, and at least one birth time here isn't exact.

Frequently asked
Are Robert Downey Jr. and Deborah Falconer astrologically compatible?
Their charts make 5 cross-aspects, the tightest at 0.65° and 1.61°. 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.
Why isn't there a house ring on the chart above?
At least one of Robert Downey Jr. and Deborah Falconer doesn't have a curated, non-estimated birth time, so a house placement would be a guess. This page only shows what a birth date alone can place.
What does trine mean between two charts?
A trine puts two placements in easy relation, a flow that takes little effort to access. Robert Downey Jr. and Deborah Falconer have 3 trine contacts between them, more than any other type.
