<P> In the first film, George is portrayed as weak and the main target of Biff Tannen's bullying . The novelization of the film expounds on George's history of weakness, describing two incidents in which he is unable to stand up for himself . In 1955, in contrast with Marty, George did not have any friends for support and was targeted not only by Biff and his gang but also other kids in school . He has a penchant for science fiction, and writes some of his own but never allows himself to share them with anyone due to his fear of rejection . In 1955, with Marty's help, he gets the courage to stand up to Biff, knocking him unconscious . As a result, he and Lorraine fall in love and George becomes popular in school for defeating Biff in a fight . In the new future, they are both happily married with George working as a college professor and being a successful writer who orders Biff around . In the alternate timeline in Part II, George was murdered by Biff in 1973 . </P> <P> George's character was greatly reduced in the sequels, and the role was recast to Jeffrey Weissman . Weissman wore prosthetics to resemble Glover and imitated Glover's rendering of McFly, and his scenes were spliced with shots of Glover from Back to the Future . The result was so convincing that many people were fooled by it . Glover did not appreciate this, and sued . The lawsuit resulted in the adoption of stricter rules by the Screen Actors Guild to prevent this situation from occurring again . </P> <P> Lorraine Baines - McFly (portrayed by Lea Thompson and voiced by Aimee Miles in Back to the Future: The Game) is the wife of George McFly and the mother of Marty, Linda and Dave . She is the eldest daughter of Sam (George DiCenzo) and Stella (Frances Lee McCain) Baines, and sister of Milton (Jason Hervey), Sally (Maia Brewton), Toby, and Joey . </P> <P> In Back to the Future, Lorraine is initially portrayed in 1985 as middle - aged and unhappy . After Marty changes the timeline, she is shown to be fit and happily married to George in 1985 . In Part II, she is still happily married to George in 2015, but in the dystopian alternate 1985 timeline she is widowed and married to Biff . </P>
