There’s not enough makeup in the world to make Fisher look human anymore.

I don’t understand why she would want to be in this film.

That is not someone who belongs on the big screen.

Ford should vanish as well.

All that is needed is Hamill’s version of Obi-Wan (Old Luke).

The word that all three seem to be coming back reeks of desperation.

Agree, I think some fans don't even know what they wish for, I don't think Hamill as an old Luke is a good idea either, these are sort of fun ideas in theory and on paper but Hamill is no Guinness. We love Carrie, Mark and Harrison but I expect it will be painful to watch even as small cameos, it will be fun for those making the film, but not so fun for the audience. Seeing these characters as old are an even worse idea than any ideas Lucas managed to realize in the prequels.
