Martin's Day (1985)

Threatened with recapture after a prison escape, Martin Stechert grabs a 12-year-old as hostage. He proves to be named Martin, too a quiet "good little boy" always obeying the rules, whom life has given only dismal loneliness and frustration in return. Soon he begins to admire "Stech" for his cheeky pranks against society and his desperate mission to make dreams come true. In a climactic moment, he chooses to stay with the man even though he could run away. Via hijacks and hijinx, they flee to the idyllic peace of the older Martin's childhood home, a cabin on a lake. But the police are close behind, impatient and trigger-happy.

Unfortunately the movie Martin's Day is not yet available on HBO Max.
