Fast forward to the first football game scene. Right after Forrest gets the touchdown, he runs into the band standing at the end of the field. There is a wide shot of this and if you look in the background, in the tunnelway, overpass, there is a red truck blocking off the tunnelway. Then, a second later, they cut to a close up of Forrest running THROUGH the tunnelway. How did the red truck dissappear within a second? [THE RED TRUCK WAS SIMPLY PASSING BY THE TUNNEL; NO ERROR HERE.]
