Mild violence.
Joe confronts Mark when he parks in his space, but Mark threatens to hit him in front of his daughter. When Joe refuses to back down, Mark strikes him twice in the face until Natalie runs out to her father's aid. Joe has a bloodied nose for the rest of the scene.
Several scenes where Joe trains with a martial arts tutor, including a moment where Joe is struck in the throat. Much of the violence in these scenes are comic and aimed at self-defence and self-confidence, including two scenes where they hit each other in the crotch.
Joe is struck in the crotch with a squash ball.
Joe and Mark race and fight each other through a supermarket to get to an empty till, and Mark knocks Joe through a display.
