 CONT: When Russ Thorn chases Linda down the corridor, she runs right  to the end of the corridor, then heads down the last row of lockers,  and Russ follows her (there is also no poster on the wall.) In the  next shot of Russ running down this row of lockers, its now  apparent that its not the end row; because there is no end wall,  and now there is also a poster on the wall behind him.
