<P> Charlie eventually catches on to Viola's plan and fights back . On Charlie's wedding day, Viola turns up wearing a white dress instead of the peach - colored dress specially made for her . This leads to a violent stand - off between the two, leading with Viola refusing to accept Charlie and states she'll never be good enough for Kevin . Suddenly, Viola's own dreadful mother - in - law, Kevin's grandmother, Gertrude Fields (Elaine Stritch), appears and they have an indignant argument, while Gertrude takes a liking to Charlie, saying she is stunning, her grandson is a lucky man, that she is an "exotic Latina", and if only her son, Kevin's father, was as lucky to find a woman like Charlie . Gertrude's resentment of Viola bears a strong resemblance to Viola's feelings of animosity toward Charlie . Gertrude even believes that Kevin's father had died years ago of "terminal disappointment", for which Gerturde holds Viola responsible . Viola counters stating Gertrude "smothered him to death", because she thought nobody was ever good enough for him (basically similar to how Viola is). Gertrude, satisfied she got her last word in, leaves; showing she still favors Charlie . Charlie decides to back--down as she witnesses Gertrude and Viola's relationship . "Nothing's going to change", she laments to Viola after Gertrude leaves the room, "In thirty years that will be us ." </P> <P> Charlie exits to tell Kevin that the wedding is off . But before that can happen, Ruby enters and talks with Viola . Viola is miffed that Charlie compared her to Gertrude, although Ruby points out that Viola is actually far worse than Gertrude, as she doesn't ever recall Gertrude trying to poison Viola once, referring to earlier at the rehearsal dinner when Viola put crushed nuts (to which Charlie is highly allergic) in the meal's gravy . Ruby points out that Viola's efforts against Charlie to make Kevin happy are unwarranted . "Whatever made you think he wasn't?" is her final point . Viola has an epiphany and realizes that she wants Charlie to stay, and they reconcile, ending the feud . Charlie then explains to Viola that she wants her to stay, too, on one condition: if Viola accepts the boundaries Charlie needs, if she is present at any family event, and if she treats her children with love . </P> <P> Charlie and Kevin then get married and when Charlie throws her wedding bouquet, Viola catches the flowers . As Charlie and Kevin drive away to their honeymoon, the film ends as Viola and Ruby walk out of the celebration . </P> <Ul> <Li> Jane Fonda as Viola Fields </Li> <Li> Jennifer Lopez as Charlotte "Charlie" Cantilini Fields </Li> <Li> Michael Vartan as Dr. Kevin Fields </Li> <Li> Wanda Sykes as Ruby </Li> <Li> Adam Scott as Remy </Li> <Li> Monet Mazur as Fiona </Li> <Li> Annie Parisse as Morgan </Li> <Li> Will Arnett as Kit </Li> <Li> Elaine Stritch as Gertrude Fields </Li> <Li> Stephen Dunham as Dr. Paul Chamberlain </Li> </Ul>
