I attended the premiere of Episode 3 with Ewan MacGregor, who went down a staircase carrying a box and turned into Harrison Ford. Which, depending on the point of view, could be disappointing...but then, not many of us are lucky enough to have our men morph into Harrison Ford, are we? :)
We sat in the very front row and my eyes were glued to the screen (which must have made me a disappointing date in high school too as that's been my attitude about movie dates...I go to watch the movie) but though snuggly, Harrison kept talking to folks around us and at one point observed a flaw in how a scene was shot with George Lucas, who sat at the end of our row. Finally I turned around and kissed Harrison very distractingly and he said, "Wow! What was that for?" Glancing around us at the folks trying to watch the film, I said, "Think of it as a community service."
On the other hand, unless Episode 3 turns out way way better than 1 and 2, everyone might have appreciated Harrison telling George exactly what was wrong with the movie :)
