Continuity: The steps up to Evans house change. In the scene where he discovers the tools, they are two sets of small steps with a handrail, but when he comes down the steps naked, there are just three steps with no rail.

Factual error: In the final scene where Congress is supposedly passing the bill, they are still in the committee room. Bills are not passed there, but in the actual meeting halls of the House and the Senate.

Continuity: At the end of the movie when Evan and God are talking under a tree in a field, God is holding a wooden staff. As the camera cuts back and forth between Evan and God, God's hand changes position from holding the top of the staff like a cane to holding the staff further down like a walking stick.

Continuity: The first bird poop on Congressman Long changes between shots (an extra smudge appears to the right of the main poop).

Continuity: The lama spit gob on Congressman Long's forehead changes shape between shots.

Factual error: Where exactly does Evan park? Members of Congress have access to underground parking facilities at the House and Senate office buildings which are located directly adjacent to but not at the Capitol building itself. Evan appears to park on the street, in front of the Capitol building, in a parking space that would ordinarily be blocked off for security reasons.

Factual error: The Ark ends up below the stairs of the Capitol, but seconds before it sets right outside the window of the committee meeting room. Those are not below the stairs.

Other: In the scene before Evan's wife takes away his kids. Evan parks in the U shaped driveway, his Hummer is the only car in the driveway, but when the wife comes outside with their kids her car is also there.

Continuity: During the flood, if you look at the clothes of the people on the ark, they are completely dry, despite several waves crashing over the boat, soaking them.

Continuity: In the scene where Evan and his family are standing on the ark just before the flood, Dylan's watch shows a completely different time than one of the spectator's watches – neither of which around 'midday' (noon) when the flood is supposed to happen.

Continuity: In the first part of the movie, Evan is driving his new Humvee and several birds fly over and poop on the windshield. Of course he turns on the wipers and it streaks all over the place. When he is done, there are still obvious and large streaks on the drivers side yet during the next 10 scenes, the streaks appear and dis-appear several times.Most obvious when he parks and walks past the front of the vehicle.

Factual error: As the story goes, two of each animal are to board the ark, one male and one female, side-by-side. Thus, two pairs of peafowls(one pair of each species) should board. Yet, in the scene where all the birds are in Evan's office, we see two peacocks(male) of the same species side-by-side, when we should see a peacock and a peahen.

Continuity: In the scene where Evan's beard keeps coming back, the shaving foam on the rest of his face - which should be unchanged - changes between shots when he looks down, and then up again and sees the new beard.
