The Kidd here...
You can count John Goodman in for THE HANGOVER PART III.
No, he won't be joining the Wolfpack to my current knowledge, but Variety reports that Goodman will be taking on a small but antagonistic role, along the lines of the slot Paul Giamatti filled in the second picture, in what is believed to be the finale of THE HANGOVER series.
Off the top of my head, I could barely remember Giamatti even being in the sequel, but he did play an undercover Interpol agent disguised as a gangster with the purpose of arresting Mr. Chow. I hope PART III doesn't steal that beat from its predecessor, because that's all we need is another retread in the franchise.
Goodman has done plenty of solid comedic work in the past, so THE HANGOVER PART III definitely added a nice piece to its cast.
