The script is characterized by numerous inexplicable mood and personality shifts in characters. In analyzing the film's abrupt tone shifts, Sestero highlighted two scenes in particular. In the first scene, Johnny enters the rooftop in the middle of a tirade about being wrongfully accused of domestic abuse, only to become abruptly cheerful upon seeing Mark; a few moments later, he laughs inappropriately upon learning that a friend of Mark's had been severely beaten. On set, Sestero and script supervisor Sandy Schklair repeatedly tried to convince Wiseau that the line should not be delivered as comical, but Wiseau refused to refrain from laughing. In the second instance, occurring later in the film, Mark attempts to kill Peter by throwing him off a roof after Peter expresses his belief that Mark is having an affair with Lisa; seconds later however, Mark pulls Peter back from the edge of the roof, apologizes, and the two continue their previous conversation with no acknowledgement of what just occurred.
