Other mistake: When Julius visits the orphanage where Vincent grew up, he begins to talk to the nun about the bed where Vincent slept and how it was near the fire extinguisher and alarm. While talking about it, he makes a motion as though he is pulling the fire alarm, but doesn't actually do so. As Julius and the nun are exiting the room, the alarm pull handle falls down on its own (no alarm goes off).
Continuity mistake: In the final scenes, the twins have had their own sets of twins. Both appear to be boy/girl twins as there are 2 in blue and 2 in what appears to be pale pink. As they walk towards the mums they are arranged boy on the left of our screen in both buggies/strollers, but when they are taken out the babies in Schwarzenegger's buggy have changed round as the baby in blue is lifted from what would be the right side. (01:40:00 - 01:45:00)
Revealing mistake: While Julius is talking to the man in front of the lingerie store on Hollywood Blvd, when the man's partner rides up on a motorcycle and tries to snatch the suitcase, we can see the stunt wire carabiner attached to the back of his jacket as he flies off. (00:12:30)
Visible crew/equipment: When Julius enters the supermarket parking lot, in the long shot we can see the stunt ramp used to lift the driver's side of the car, to go into ski mode. In this and following long shots of the stunt, we can also see the window roll cage bar directly behind the front windshield (the obvious stunt driver grips the roll bar with his left hand and steers with his right hand), as well as the top of the seat supports behind the front headrests. (00:30:55)
Continuity mistake: When Arnold kicks down Mitchell Traven's door, you can see the hinge intact at the top right of the door frame. When the camera faces Mitchell Traven, then Julius, you can see the door frame again and the hinge is damaged.
Audio problem: When Vincent is receiving the parking ticket for being in the handicap spot, at one point we hear him say "Handicap my ass" but his mouth is not moving. Clearly dubbed in later.
Answer: Because the offspring of this experiment was meant to be studied, researched. Mary-Ann showed signs of maternal attachment toward the end of her pregnancy, which the scientists involved felt would hinder the experiment due to her not wanting her baby poked and prodded at all day, every day. So she was told her baby died at birth and she was sent on her way. There was no point even mentioning the second baby since she never knew she was carrying twins in the first place.
