That still seems very unlikely. Maybe he just means they had to do a couple three takes of each scene and there were a couple deleted bits. I just can’t imagine they filmed that much extra. Maybe the actor just thought it was a lot because that was the first Rumpel centric episode.
Robert Carlyle has been acting for 30 years. I would think he knows the difference between filming multiple takes of the same scene and filming different scenes. I imagine the 60 minutes is an estimate on his part but I would trust him to have a pretty good idea of how much they filmed.
