we do have a verified time of birth for 5:41 AM Beirut.
So the Ascendant is Leo with Mercury and the Sun in the Ascendant and receiving the direct 7th aspect of Saturn. Saturn itself is in its own house in Aquarius. Of course, the aspect of Saturn on the Ascendant gives his international fame.
The presence of the Sun and Mercury in the ascendant most likely give him his quick insight and temperament, that is responsible not only for his not finishing high school (not playing by the rules) and his high intelligence. He is said to have memorized all the lines for Hamlet before he auditioned.
He is presently in his Mercury period (1996-2013). Of course, some of his most successful films occurred during this period (Matrix).
You will also notice that he had a stillborn child in 12/1999. That was a Mercury/Venus/Venus period. Notice that Venus the significator of baby girls is in his 12th house.
Notice that he does have Saturn aspecting Mercury and the Sun and this can lead to nervousness. In fact he has dyslexia.
You will also notice that Mars and debilitated Saturn are aspecting the Sun in the 12th divisional chart indicating a propensity and indeed he has already had a severe motorcycle accident in 1988. This was a Saturn/Sun period.
Another mysterious thing about Keanu is his sexuality. Although he did famously have a "straight" relationship with Jennifer Syme, the rumor mill is there about his being gay. Now what I look for is if Mars and Saturn are aspecting the ascendant; if Jupiter is also aspecting then the person will be "straight". If not, bi-sexual. As you can see in his chart, Jupiter is not aspecting the Moon, the ascendant, or the Sun.
