Your right, it probably wasn't an oversight, as I stated above. It was a financial move. I explained why in my previous post.
And just because they where involved with another franchise 30years ago doesn't really mean much. They didn't have the rights to the figures then either. Nor was it the same situation, as Lucas film never lost control of the rights to Star Wars. Being involved in a production of a movie does not mean you own the rights. They where essentially an investor. And they way movies where distributed back then has changed dramatically. Back then the only way to get a wide release (lots of theaters) was to partner with a major studio, as they had exclusivity rights with many theaters. That also played a part. But Lucas never licensed the film rights to fox. Fox did not have the likeness rights to Star Wars. So I guess in regards to likeness rights it's the same, but outside of that the situation is completely different
