On May 14, 1986, Marty McFly prepared to leave for 1931. George, seeing Marty in his period outfit, questioned why his son was dressed in that manner. When Marty lied that it was for the school play, George surmised that the play was 'Grapes of Wrath' (his words), based on Marty's clothes. When Marty confirmed this, he showed interest in the play, asking who Marty was playing. When Marty could not answer, George assured him that he didn't have to explain what was going on.
Behind the scenes
- The Grapes of Wrath did not have an official stage adaptation until 1988, so such a performance at Marty's school would have been based on the original novel or the 1940 film adaptation.
- George shortens the name to 'Grapes of Wrath', omitting the 'The'.
- The novel, having been published in the 1930s, is a fitting excuse for Marty's clothes, given that he was dressed for 1931.
