For decades, next-door neighbors and former friends John and Max have feuded, trading insults and wicked pranks. When an attractive widow moves in nearby, their bad blood erupts into a high-stakes rivalry full of naughty jokes and adolescent hijinks.
Unfortunately the movie Grumpy Old Men is not yet available on HBO Max.
