Most of the Price movies I've seen are his horror comedies like Theater of Blood, Comedy of Terrors, The Raven, etc., which I like, but it was nice to see him play a more serious role for a change. Still, Cushing would have been very right for that part. I imagine he would have been a lot like Frollo in The Hunchback from Notre Dame. I also wouldn't have minded seeing Donald Pleasance play Hopkins, especially since the director wanted him originally.
That said, I think he was the only actor that could’ve done Theatre of Blood in that manner. Just a perfect performance for an actor of his caliber.
