Sandra Oh has crossed borders and cultures to become a successful actress both on television and in movies. Born on July 20, 1971 in Nepaen, Canada (a suburb of Ottawa) to Korean parents, Sandra is skillful in both comedic and dramatic roles that show off her deep feelings and sharp sense of humor. But most of all, it's her approachability that draws in viewers and makes them feel so close to Sandra. Her personal style is due to having the Sun, Venus and Moon in watery, sensitive Cancer. This is a sign of family, familiarity and belonging, which is one reason Sandra feels like she's one of us. The Sun here is conscious of the power of emotions, and Sandra has learned to express this power through the art of acting. While she's clearly very bright, the presence of three planets in astrology's sign of caring makes us concerned about her and the characters she plays. Even when Sandra's being snippy or sarcastic on-screen, it's still obvious that there's a highly sensitive woman behind her sharp or playful words.

Mercury, the planet of communication, was in Leo when Sandra was born. This outgoing sign adds confidence and drama to self-expression, brightening up the sometimes serious Cancer personality. Leo is the sign of the performer, so Mercury's presence here makes Sandra comfortable talking in front of the camera or a live audience. Occasionally, Mercury in Leo can bring some heaviness that slows down conversation, but not here. Mars, the planet of action and initiative, was opposite the Messenger in Sandra's chart, turbo-charging her mind with high-speed energy and a sense of urgency. Spontaneity, a quality associated with Mercury-Mars contacts, was evident when the 'Grey's Anatomy' star was a member of a National Champion Canadian Improvisation Team in the late nineties. The creative impulses of Mercury in Leo are not only pushed by Mars, but the warrior planet's presence in inventive Aquarius allows Sandra to shoot her witty arrows from a wide variety of perspectives. This range of comedic talent has been obvious to Sandra's fans from 'Arliss' to 'Under the Tuscan Sun' to 'Sideways.' Her wise-girl persona shows off her brains, but like a good Cancer, feelings count more.

Sandra once said, "We actors, we're a fragile bunch, and yet we need to be strong because 90% of our lives is rejection. You have to figure out what really is important." It's this very fragility that makes her such a compelling figure on-screen. No matter how fast she's talking or flying through the hospital halls as Dr. Christina Yang -- or in any other part -- Sandra makes us want to protect her. She doesn't need our protection, though. With her hard outer shell, this Crab knows how to take care of herself.
