Are the guest voices credited and could anyone name them with their role (or take a screenshot)?
Is Gene Wilder (remember the old rumour?) voicing Ivo Shandor and who is the new voice of Vigo?
Found nothing yet on IMDB or Wikipedia.

known/confirmed:
Dr. Peter Venkman (Bill Murray)
Dr. Raymond Stantz (Dan Aykroyd)
Dr. Egon Spengler (Harold Ramis)
Dr. Winston Zeddemore (Ernie Hudson)
Janine Melnitz (Annie Potts)
Walter Peck (William Atherton)
Mayor John “Jock” Mulligan (Brian Doyle-Murray)
Dr. Ilyssa Selwyn (Alyssa Milano)

I think I read somewhere that Kiefer Sutherland was the voice of Slimer. Hard to believe though.

Gene Wilder was quoted with:

I currently am working on a project with Mr. Dan Aykroyd. By the way. Do you believe in ghosts?

It didn't sound like Gene Wilder voicing Shandor. I did notice one of the other Murrays in the credits, and I thought Dr. Rutherfurd was Bill Murray at first doing a different voice, so I'm thinking he was voiced by the other Murray (I think it was Joel Murray).

I remember reading that someone involved with the game said that there were going to be some celebrity cameos, like Eddie Murphy but I didn't hear any.

Bryan Doyle Murray (Bill's brother) is the voice of the Mayor

he also played the psychologist in the nuthouse in GB2

I realize that, but if you look at the credits there is a third Murray. I don't think it's a coincidence either.

Considering that Shandor had one line that I remember when he was not possessing anything…I highly doubt that Gene Wilder would have been brought in for that

Actually no he doesn't have one line he had a whole rant about how he will rebuild the world not just I AM A GOD! remember?

Slimer was voiced by Troy Baker. I met him at AnimeBoston and we talked GB for a minute.
