I'm ging to try try and describe the movie as best as I can hope it is enough. When I was younger I watched a movie with a woman in the desert running from some type of alien/creature type thing. I do remember that she does fight it at some point near the end. And I do remember her flying away in a plane. It could be a 80's or 90's movie. I wish I could give more details. Will be grateful if someone is able to help. Pretty sure it would be considered a sci-fi movie.

Maybe one of these?

I'm sorry muffie but none of those were correct but thank you for trying. I will try and describe a little more detail umm the alien/creature thing kind of reminds me of a predator. The woman in the movie is blond and she isn't wearing much clothing kindda like a Amazon. There is a few rebel tpe people also in the movie. At the beginning there's a block type object and I think it is either her or the alien/creature that gets out of it.

Try this:

(at about 1 min you get a quick glimpse of a large cube thing, and then the 'predator' thing, and the gal running through the desert... )

Sweet this is the movie I have been looking for. Thank you very much for taking the time to help me. Again thank you and take care

Yay! :)
