I don't think I've ever seen that, and now I want to. But to me, Glenn Ford had an annoying trait that became more annoying the later in his career he got. That sort of hesitating, stammering thing he does. It's like he said to himself: "Real people don't always know what they're going to say next. So I should act more like one of those real people, and make it apparent that I'm thinking of what to say, working out what I'm trying to say while I'm saying it, just like real people do." The problem is, unlike with Jimmy Stewart (who somehow made the stammering thing feel like part of the character), with Ford you can always see the "actor wheels" turning, the intention to stammer, in his head. At least that's my subjective reaction.
