You glance out your front window. You do a double-take. What is it that you see?

Like those glances in movies...you know...when they glance and then do a double take? Suddenly out of nowhere is their ex! Some actors are bad at this maneuver...some are good... Pretend you're doing this in your front window...imagine: you might call out: "come and see this! You won't believe it!" It takes a few frustrating moments for your peeps to pay any attention...The 2nd...and underlying question: which movie might I be talking about? There could be a few....ha. And post pic might give a hint.
