 Crispin Glover (qv) played George McFly in  _Back to the Future (1985)_ (qv), but was replaced by  Jeffrey Weissman (qv) in Part II. Weissman was made up to look  like Glover so that this film could incorporate excerpts from the  original. All shots of Weissman are either from the back, at an  angle, or with Sunglasses so that the audience wouldnt notice that  it is a different actor.
