In the stray moments when his performance lapses into a Ralph Kramden imitation, a look from Ullman is all that's needed to remind him who's boss. And yet Ullman doesn't slight the sweetness that characterizes her work. She's one of those performers who seem to have an instinctive audience rapport. You know immediately why Ray is crazy about her, and you ache for her when she overhears her taste being denigrated. It's a little delight of a performance.
Grant takes to playing a bastard.
He lets something self-satisfied and prissy and slightly acrid worm its way into his persona. The slyness becomes him. If he could find a way to work a bit of this nasty-mindedness into his romantic leading roles, he might give himself an edge that could make him more appealing than ever. She's simply flabbergasting. Groucho Marx once said that Margaret Dumont was so good because she didn't get the jokes.
