 CONT: When Lulu is lying in bed being questioned about her  medication, she lights a cigarette. She takes it from her mouth in  her left hand but in the next shot it is in her right hand as she  ruffles her hair. The cigarette is in her hand with her arms crossed  over her head but in the cut back to the shot of Ben as he talks she  has taken a puff even though no time has passed for her to do so.
