I love all the Wizard of OZ refferences in SG-1, always make me chuckle
I never actually noticed the Starwars Refferences though now you mention it there seem to be a lot of similarities.
There is also a refference to aliens I believe when Daniel cant remember his way to the cargoship.
I was going to take those screenshots for you to compare but for some reason windows refuses to take them, it used to work
