I’ve noticed when it comes to wholesome roles there seems to be a pattern to cast the exact opposite in terms of the real life actor. Stephen Collins as the minister in Seventh Heaven comes to mind. The casting people know and I think it’s their big FU to the normals.
Even Michael Landon was not the person he portrayed
I wouldn’t doubt it.
I remember the “sermons” he would work so hard on were dull and anything but like a real preacher would deliver.
