Tony Peterson — aka the fine Jerry Lacy — has shown up to lay down the law. Literally! And if you ever see him interviewed, watch/read it. Broadway’s greatest Bogart and The Trask. He married Julia Duffy, too! He is A Man.
They had to know he was playing The Trask, so this must have been some way to slide him into the ensemble. This ensembles approach really adds to the WIZARD OF OZ feel to the flashbacks.
