 During the battle with Klingons, Troi, played by  Marina Sirtis (qv), takes the helm when the conn officer is  injured after a computer station explodes. The director wanted this  action sequence done in one take in order to fully capture the  genuine reactions of the actors. During the filming, however, Sirtis  burned her bottom after she sat on a burning piece of debris that  had landed on the conn station chair. This was the take used for the  movie, however, it cuts away right as Sirtis sits on the chair.  Sirtis was not badly injured and continued filming the scene  afterwards.
