During the scene where Robert Kelly-Schleyer (Sam) is painting, he actually is scribbling joshing statements about the US Navy onto the canvas; Kelly-Schleyer is a former US Marine. Off camera this is being observed by Jason Klein (Ryan), a former member of US Navy Special Operations, who is unable to respond. The two kidded each other throughout the filming as Marines and Sailors have been doing since the formation of the United States Marine Corps in Tun Tavern on 10 November 1775.
