Continuity mistake: In a matter of 15 seconds between David's ship exiting the hangar and shooting 20 miles upwards into space, shadows on the ground indicate very different positions of the sun. (00:51:05)

Directed by: Randal Kleiser
Starring: Paul Reubens, Cliff De Young, Veronica Cartwright, Joey Cramer
A little boy named David, goes out into the woods, and falls down into a ravine. He wakes up and discovers that he is in the future. So, he goes back home, but nobody is there that he recognizes. He eventually finds his parents, which are visibly older now, especially his brother, who is a lot older now. He then finds a spaceship in a nearby hanger and a robot inside the ship that operates it. It recognizes David and takes him on a trip around the world. David eventually decides that he can't stay in the future anymore and asks the robot to take him back to 1978. The robot agrees and takes him back.

Question: Even though it's not technically indicated in the film, I always wondered if the young blonde lady watching the spaceship shown for a few seconds in 1986 just before David returned to 1978 was Jennifer (the 12-year-old girl David had a crush on in 1978). She looks roughly 20 years old now herself and I thought that could be her just to show what she looks like now (maybe there was a deleted scene with her in it). Was this a correct assumption?
Answer: The only people with different young and old actors were Jeff and Carolyn. The scene with young Carolyn would have been after he got back from the future and was filmed, but cut for pacing reasons.
Answer: I can't directly answer this, but I was watching this movie just now, and didn't take in the girl at the beginning's (Jennifer's) name, so when Sarah Jessica Parker, Carolyn, appeared I then spent the rest of the movie assuming that she was going to turn out to be the girl he was crushing on in 1978, especially when Carolyn even told him he was cute (which is kind of a weird thing for a 20-year old to say to a 12-year-old if there isn't a plot reason for it). I do wonder if that was in fact the originally intended idea that was changed for whatever reason before the movie was completed, and if perhaps he was meant to go back to 1978 with the knowledge that she found him cute and therefore a new-found confidence to ask 12 year-old her out.
