Please explain this to me.

1. Women color their hair all the time. Some women change hair color as often as they change clothes. Why is this even a question?

2. It's a bad movie. Bad filmmaking, bad plotting, bad continuity. There is no explanation for the inconsistent depths in the underground chamber(s).

1. I'm going to assume you just had a brain fart when you asked this question. Hair dye.

2. Could be a few different reasons for this. The dad's estimation of how deep the hole was could have been incorrect, the hole could've been on top of a hill (not sure on this one since I wasn't paying too much attention to the landscape in the movie), or it could've just been a mistake in the movie.

1) i have 5 sisters, 4 have brown hair and 1 is a red head, all are natural colour, none of my sisters use hair dyes, these things just happen.
2) he is talking to his wife about what happened from his experience, and probably imagined it to be deeper than it really was, poor lighting and being under stress can do that, and when she pushed her kid thru the hole, she climbed up a little so it probably was really only about 10 to 12 feet, assuming that the land slopped between where she entered and exited the underground part of the building.

she always did enjoy a good squeeze.

1.the Joyce (Katee Sackhoff) is originally blond but shown as red head in this movie, and also she was the sister of Lisa and Lisa was black hair lady,i mean how this is possible in one family genetically.

Joyce had red hair because Katee Sackhoff looks super duper hot as a redhead.

1) Well, it's actually perfectly possible. It all depends on how your mother and fathers DNA arrange in order to make you. I have a friend who is a ginger, and he's the only one out of his 4 siblings.

But that's not really an issue because Joyce's hair is clearly not naturally that shade of red. Nobodies hair is naturally that color.

2) That may seem like an error, however, the earth is not a perfectly flat surface. Where they exit the hole may be at a lower elevation from where they entered. Since the topography of the land is never brought up, we can't really say it's an error. It does feel strange, but isn't necessarily an error.

All that said, don't get the impression that I think this movie is good. I certainly don't. Just pointing out that these are not really among the issues with the film.

Prof. Farnsworth: Oh. A lesson in not changing history from Mr. I'm-My-Own-Grandpa!

its genetically possible. not only gentically possible but its more common than people think. it depends on many factors, one thing is their parent genes
