Mos Eisley Cantina: More than 70 characters have got their proper names. Due to the early Elstree scenes, there are still several characters who don't have a name. Most of the time, they're seen on the left side.
# The left side in the Cantina is terribly dark. There are three Spacers. One is Danz Borin, but who are the other two? One wears a yellow spacesuit and even sits next to Borin.
# Also in the dark spot is "The Colonel". He's a Lutrillian like Solomahal.
# There's a strange spacer (no. 3) behind Ben in the Cantina when he's talking to Han.

# Officer in Death Star Conference Room who sits with his back to the door opening (not Cass).
# When the Falcon has just arrived in the Death Star there is a scène where an Officer without any rank insignia's says to Stormtroopers "Come with me". He should be a Stormtrooper Officer.

Rebel Alliance:
# Who is the Rebel Officer who accompanied Leia when she kissed Luke good luck on Yavin 4? Is he from Alderaan? What is his rank?
