Early on in the movie, Stephen tells Fran to meet him on the roof at 9:00pm, yet when they take off from the dock, much later, a clock near the skyscraper turning its lights off reads 6:00pm. Figure it out.
Sorry, but this is dumb, if you have the directors cut you would know that fran was suppose to meet steven on the roof of the news station, from there they go to the police docks to pick up roger and peter who havent yet arrived. Now there is nothing that said they were going to pick up roger at 9:00, and anyways no telling what time they left the news station, or where they went befor they got to the police docks. So it could have been 6:00 Am, remeber the clock did not say P.M. you are just assuming it. the normal copy of dawn does not have the full police dock scene.
