According to this question (better citation needed), Yoda said to Luke: The Force is strong with your father, you, and your sister. Did Leia ever use The Force? Answer Within the movies - there's a couple of points where there seems to be an affinity between Leia and Luke. Whether this is because of Leia's latent talent, or Luke's own force ability, is up for debate. 1. She gets Lando to turn the ship around to rescue Luke from the bottom of Cloud City, because she "hears" him call out to her 2. She "knows" that Luke got off the Death Star II before it exploded In the Expanded Universe, however, there are many examples of Leia developing her force ability. While these are not the same canonicity as the movies themselves, EU canon is still held to be strong wherever a movie doesn't outright contradict.
