Befitting a movie about a man losing his memory, Frank Langella's character in Robot & Frank is also named Frank to keep things simple. And true to the title, his companion is a robot, assigned to care for the old man. Afflicted with not-explicitly-stated-but-obviously Alzheimer's disease, Frank gradually reveals himself to be a retired thief, still capable of pulling off small grabs and even intricate break-ins but less able to remember what it is he wants to steal, or why it is an awful idea in the first place. Initially resistant to the idea of having his diet and activity controlled by an eerily pleasant, vaguely humanoid being, Frank soon relents when he learns that he can convince his caretaker to assist in burglaries.
That Frank's children (James Marsden and Liv Tyler) did not think to program the robot to prevent their once-incarcerated father from committing further crimes speak to how little they think the addled man can do, an unwitting admission of their perfunctory sense of filial duty. As Frank slowly bonds with his personal trainer and eventual accomplice, the robot becomes a complex repository for the emotionally (and, often, physically) absent parent to both vent his frustration with his kids and to vicariously attempt to make amends with them. So effortlessly does Langella invest these feelings into the emotional void of his "co-star" that Robot & Frank works best when its thin commitment to a narrative evaporates and lets the actor simply inhabit his odd role.
