Dawn Of The Dead - Continuity Errors & Hidden things

As with all films Dawn has continuity errors, Im only aware of a few but I think the most major one is the way the blood on Rogers face in the truck disappears when the camera flashes to peter and then back again, or was it invisible ink ;P Can you think of anymore?

There are a few 'hidden' things in Dawn, the first one which should make fans happy is that in the television studio at the start both Romero and his wife can be seen arguing over lists of rescue centers. Also in the directors cut there is a scene where Fran and Stephen are confronted by some policemen who are trying to stop them stealing the helicopter, one of the policmen here is none other than Captain Rhodes from day of the dead, although in most cuts this scene isnt available and Rhodes was only briefly seen in the background. He was of course dissapointed at his part being cut from the film. Another bit which I find funny is when the 2nd police man keeps asking for cigarettes and nobody will give him any, in the directors cut this bit goes on unneccesarily long and he goes on to say things like 'we need cigarettes' & 'can we stop and get some cigarettes'. Im not sure what the significance of him saying this is but maybe it is to show that through all this mayhem people are still addcited to things or still cant do without their luxuries. Then to highlight the 'cigarette' obsession again they all pullout cigarettes and start smoking them as soon as the helicopter takes off, Peter looks around and just laughs (exactly as the viewers did!).
