Paul Giamatti Reveals the "Real Significance" of His 'Downton Abbey 3' Return

When it was announced that Paul Giamatti (The Holdovers) was going to make a return to Downton Abbey: The Grand Finale, fans were a bit taken aback. When the two-time Oscar nominee first appeared in Season 4 of the series, he didn't feel like the kind of character that would make a comeback — and this was supported by the fact that he was only in one episode of the entire series. In a new interview with Entertainment Weekly, however, Giamatti revealed that his character will be extremely relevant to the final chapter of Downton Abbey.
