A fine actor from a pre-CGI era of cinematic greatness that will likely never come again.
Agreed, but in a career that lasted from 1956 to 2013, he transcended both eras: both the pre-CGI era and the CGI era, for one of his greatest roles was as Anton Ego the French food critic in the Disney/Pixar CGI animated "Ratatouille" from 2007. He will be missed, and R.I.P. Peter.
And, oh yes, we have one more chance to see him in a new role, as his his last role is as Gallus in "Katherine of Alexandria," which was scheduled to be released this year, but more likely will be released next year in 2014.
