Damnation Alley or Logan's Run (2010)?
I thought of the "Logan's Run (2010)" remake, then I remembered reading about a remake of the movie "Damnation Alley (1977)". On the discussion board for the latter, a person does mention that there will be a remake of "Damnation Alley (1977)", and it will have actor Bruce Willis as Tanner, and actor Gary Coleman as Keegan (?)...whether that is true I do not know for a fact, however, I looked on Bruce Willis' page, and I wasn't immediately able to find anything about this "remake" as informed...perhaps it is something that is being developed and is not yet listed or publicized there on IMDb for Bruce Willis.
So, which would be easier to remake?
I would guess "Damnation Alley" (1977), as it had (as I remember it) humanity and interaction, with characterization also. The special effects were present, yes, and it was not so much of a futuristic, material or object expense.
However, I still enjoy each existing movie, for what it is, sci-fi classic. I do not beleive one is better than the other (I respect each movie for what it is, and the actual work and co-operation that made them what they are).
