Scifi Movie out in DVD you should see
Robot and Frank, starring Frank Langella, Peter Sarsgaard, James Marsden, Liv Tyler, Susan Sarandon, Jeremy Sisto, Ana Gasteyer and Jeremy Strong.
It is a caper comedy about Alzheimer's, in an SF mode.
It is filmed with a budget derived from the spare change found in the producers' couches, but well worth your time all the same.
Morals are what you do to other people. Other people, what we call society, are essential to human happiness. Therefore, morals are the path to happiness. My morals, your happiness; your morals, my happiness: It's a fair trade.
