Hello Jake! I really liked back to the future when I was growing up. I found it to be a great trilogy, not a single bad movie in there!
. I think this script would be fantastic as the wild western setting is a fantastic location for a back to the future film. However, I think there is a better alternative to the 'wild west' setting, how about setting it in Nazi occupation Germany during the year of 1939, using this setting you can explore anti-jew and racial tensions, whilst still using comedy to express it's central ideas. You can take note on how to make racial tension funny whilst still making a good point like other classic movies such as white chicks.
Further comments could be made on my comments, i had a brainstorm on some dialogue that would express this. I think some updated lingo could help the movie such as bellow:
Motry: Yo, Doc fam, this ain't so lit a time for dem white money nose jew niggazz
Doc: Yeah that Aldof brav ain't so nice to dem bank owners down the street
Morty: Yeah Fam
Doc: Yeah you expressed that entire situation better than i ever could
Morty: Lit af
Doc: Oi, Listen morty we ain't hit to spit no anti-Aldof ryhmes dog
Morty: What rhymes brah?
Doc: Lit
Morty: Then what we here for if it ain't for dem lit ryhmes?
Doc: We here to neck that Aldof dog
Morty: How we gonna do that? Lit?
Doc: Change history, We lure him in with that promise of white chicks dvds, but since he is the slimiest snake, we hit him hard in the gooch with the white chick dvd
Morty: Yo fam that sound of the lit af yo man dawg.
I think it would really add to the character development and improve the storytelling, Get ready for a sequel! back to the future 5 here we come! Cheers fam.
