That was some grudge, don't you think? Since The Robe was released back in 1953, and they divorced in 1960 after they married in 1950. Come on, you made that up. I don't know the reason for the divorce, but I hardly doubt it was because of that.
The Robe was being filmed early in 1953. Burton made some critical remarks about McCarthy and the HUAC. Some people believe this may have prevented him from ever winning an Oscar.
