The movie is called Sam and Kate, but it is equally about Bill and Tina. And it is about the actors who play them. Bill is played by Oscar-winner Dustin Hoffman. and his son Sam is played by Hoffman’s real-life son, Jake Hoffman. Tina is played by Oscar-winner Sissy Spacek, and her daughter Kate is played by Spacek’s real-life daughter, Schuyler Fisk. That real-life connection gives the film extra interest and extra grounding. There is a palpable sense of trust in the scenes of Sam and Kate interacting with their parents that lets them show frustration without making us for a moment doubt their love.

It will take a while for Sam and Kate to learn that they have a lot in common. They each lived somewhere else and have returned to a small town to help care for their parents. Bill is cranky and demanding. We first see Sam resignedly sitting on a chair in a huge big box store as Bill rides around on a scooter annoying the staff. Tina and Kate have a warmer relationship, but we will learn that Tina is more dependent on Kate than she seemed.

Sam loves to draw but he is stuck working at a chocolate factory. His Kate owns a bookstore. Both are feeling isolated and lost, though Sam has hoped that Kate will help him feel less lost. He awkwardly tries to ask her out in her store but she says she is not dating at the moment.

On Christmas, all four attend the same church service. When Tina’s car stalls in the church parking lot, Bill tries to help, and the four get acquainted. Bill takes Tina on a date and Kate agrees to let Sam take her out.

First time feature riter/director Darren Le Gallo is better with the in-between moments than the plot developments, which is often the case with beginners who have not yet learned to trust the audience. When the chaacters are just interacting quietly they convey a great deal and the events interrupt the delicacy of those scenes. Jake Hoffman, very impressive in small roles in “The Wolf of Wall Street” (as shoe designer turned felon Steve Madden) and in the otherwise disappointing “Otherhood” moves smoothly into a central role. And Fisk, an engaging screen presence going back to 1995’s “Babysitter’s Club,” has a lovely, expressive light. Watching them together as Sam and Kate begin to open up despite all of the baggage and self-protective distance and fear of vulnerability is touching and a reminder that it is those in between moments that can matter most.

Parents should know that this film has a non-explicit sexual situation and some crude sexual references, strong language, alcohol and marijuana, and a sad death.
