Visible crew/equipment: When Memphis (Nicolas Cage) is speeding up to take the final jump on the bridge, you can see the camera crew on the other side of the road filming, if you look closely you can make out the shading devices used exclusively to block out the sun from the camera. Look to the left of the jump just before he hits it. (01:39:30)
Visible crew/equipment: In the "Director's Cut" version, when Memphis makes the impossible jump over the accident on the bridge, you can see the fixed camera inside the car when it first hits the bridge deck, but it mysteriously disappears after that. (01:49:05)
Answer: That billboard was part of an anti-smoking campaign from about 18 years ago. The image mocks the iconic Marlboro Man, with the cigarette in his mouth flaccid and drooping. The word "Impotent" is rendered large in the same type style as the old Marlboro logo. In much smaller text (not visible in the film), the sign reads, "WARNING: Smoking Causes Impotence."
