I have his autobiography, and Dwayne Hickman (“Dobie Gillis”) was at one time a very devout Catholic. Went to Catholic schools all life, at one point even considered becoming a Priest, and co-star (and later Gilligan star) Bob Denver went to Loyola University with him (however, it wasn’t mentioned if Denver was actually Catholic or not. Did Loyola accept Non-Catholics?). Furthermore, the guy that played Dobie’s father on the series, Frank Faylen, was also Catholic, and was attending the same Church as Hickman before they even worked together on Dobie!
I don’t know much about Faylen or Denver beyond that, but in his book, Hickman says that he got into some kind of meditation (exactly what kind is escaping me at the moment), and eventually, unfortunately, left the Church, although he stated he had no bad feelings towards it.
