Game Of Thrones: 18 Actors Who Were Replaced

4. Ian McNeice (Illyrio Mopatis)

The Replacement: Roger Allam

That unaired pilot included a number of other alternate actors - with Rob Ostlere replacing Jamie Campbell Bower as Waymar Royce and Dermot Keaney replacing Richard Ridings as Gared for the opening sequence - and the Magister of Pentos was also originally played by someone else entirely.

Ian McNeice was cast as the scheming Illyrio Mopatis for the pilot, but when the show went to full season, he was undone by a scheduling conflict and was replaced by Roger Allam.
