Yesterday saw the Man Of Steel film a Smallville scene in the the Sugar Grove area near Plano, Illinois.
Potential spoilers, ahoy!
Apparently, the Kents are directly in the parth of a tornado.
Per the video, people are running away - and we see Kevin Kostner (Jonathan Kent) waving people on, as to direct them to safety. I think Henry Cavill (Clark Kent/Superman) and Diane Lane (Martha Kent) are also present.
Also, we see a jet engine placed directly in front of the Kent car.
Once the people are far enough away, will we see Superman tackle a Tornado?
Check out the video below and some pics.
