I bet you will be surprised at who it is.
I was surprised that such a prolific actor that held such a stage presence didn’t do love scenes. Can any of you remember one? To think Patrick McGoohan was up for James Bond and The Saint.
McGoohan was one of several actors considered for the role of James Bond in Dr. No. While McGoohan, a Catholic, turned down the role on moral grounds, the success of the Bond films is generally cited as the reason for Danger Man being revived. (He was later considered for the same role in Live and Let Die, but turned it down again.)
Currently there is another Catholic actor Neal McDonough who refused a love scene but that is not the name I was looking for.
