The Death Star officer who tells Vader "There's no one on board, sir. According to the log, the crew abandoned ship right after takeoff" is dubbed by none other than Harry Shearer, of "The Simpsons" fame. Only a couple places online mention this, but I spotted this one myself first.

I messaged him on Twitter, let's see if it works.
