They should remake both movies, but like shot for shot remake, with the original cast. Ali Sheedy, Steve Guttenberg, even Fisher Stevens in problematic brown-face. Spend a ridiculous amount of money on CG and practical effects, all to make it look as close to the original movies as possible but with old people.
I don't picture Guttenberg as someone that can appear in public anymore. Like he's physically unable to go out. That's my head cannon.
Edit: I was curious and searched. He just looks like the guy next door now. Im kinda disappointed. No where near what i was imagining, and not anything like he used to look like. Just... middle of the road.
I also never realized how jacked he was back in the day.
