OK, it's only a fantasy, but it could be done. Now, the technology exists to realize Peter Gabriel's vision that simply couldn't be done 40 years ago. Of course, Gabriel would have to be convinced to write a script. And Genesis would probably have to rerecord some music (like Pink Floyd did for "The Wall". All the CGI required would cost a FORTUNE, and what studio could be persuaded that it would make a profit? But it's nice to dream...
