I’m trying to handle some of it, but I keep running into it sounding unnatural when I try to separate the different parts of Sir Ridley’s clip. Here’s one that incorporates the reverb and some additional fading/other items.
I’m not a big audio editor, so I suspect that it still sounds rough. It’s doable and a more talented editor can find better clips/equalization/reverb effects to make it work. I would suggest finding a clip where James Earl Jones says a drawn-out “mother” (probably from his Bible audiobook). One of the more audio-minded people here could really make this idea a reality for Adywan’s edit.
This fan-made Steven Universe spoof of the “I am your father!” scene replaces “father” with “mother”.
