Yeah, the young black girl is confirmed to be Lando's daughter, but it's never mentioned in the film. There's a lot of things in Star Wars, especially this trilogy that get confirmed in the novels and comics. I shouldn't have to consume the other media to understand what's going on. Now.... that being said, the movies were fine as a stand-alone, but there are gaps and little things that don't make sense unless you read the novels and comics. It's the same for other properties as well. I watched the first season of the Witcher on Netflix, and was somewhat confused, and someone told me "if you don't read the book or play the video game you won't get it". I shouldn't have to! Each "thing" should stand on its own. It's cool if they tie in to each other, but if I can't read/watch/play one without needing to watch or read the others, they're poorly written. If that girl is Lando's daughter, it should be mentioned in the movie. Having the director tell us in an interview after the fact is poor writing. Having it be part of a story line of a comic or tie-in novel is just merchandising that I don't want to be part of. And poor writing.
