Okay, took some extra time to look a bit more closely at the Lucasfilm logos, and it does look like a different font. But it was helpful to take a closer look because it looks to me like the SW Lucasfilm may be using the same font (though capitalized and more rounded) as the ALTA.

The holes in SW seem more oval... but when you overlay them, they don't exactly match up. And in order to make them match up, some letters needed to be decreased in width, and others increased. That would only make sense if you used a different element for each letter, which is probably very unlikely I would guess. But even if you adjust every character, they still didn't match up exactly, because you have the different curves and hole shapes.
