George McFly is the husband of Lorraine McFly and the father of Linda, Dave and Marty McFly in Back to the Future. George is portrayed in present-day 1985 as middle-aged as the series spans from his teenage years in 1955 to being a senior citizen in 2015.
George appears in "Finders Keepers" when Lois accuses Peter of being played for a fool like George. A cutaway shows that George is very much aware that Marty was the one that appeared in their past as he sets the carpet on fire as he mentions in the film. George takes off his belt as he pursues Marty to get more answers from him.
George is voiced by Seth MacFarlane.
