Key scene missing from the film
*possible spoiler*
Biff makes a phone call to his mother from the restaurant. Linda is ecstatic when she answers, remarking that "she's so glad Biff called." She tells Biff that the rubber hose is gone from behind the water heater, thinking that Willy had removed it and disposed of it. Biff tells his mom that HE removed the hose. Linda is crestfallen.
To me, this is a very key scene in the play. Linda was feeling that the storm had passed and everything was going to be okay. In a moment of irony, it's Biff who crushes her spirits for good--and so casually at that. Linda tries to get back up at later points in the story, but always seems shaky. She even gets almost violent with the boys at one point, revealing her frustration at being powerless toward the overall situation.
Another key part of the scene mentioned is when Linda tells Biff to make sure he has his comb, indicating that even she believes image is critical to success.
