The funniest Star Wars humor is usually the simplest. This is nothing but a sight gag strung out to eight minutes, but it had me in hysterics, at least for the first 90 seconds. What makes it work is the letter-perfect recreation of the costumes and set. You’re in the honest-to-goodness Star Wars universe — except, in the blink of an eye, you’re not.

After the initial shock the script writes itself. But stick with it. Part three has its moments.
