Clifford
(1994)

Uncle Martin (Charles Grodin) finally takes Clifford (Martin Short) to Dinosaur World after Clifford destroys his life.  Martin puts Clifford on the "Larry the Scary Rex" ride and makes him ride it over and over while continuously increasing the speed.  The ride finally breaks and Martin saves Clifford's life.  Martin is still angry with Clifford though and refuses to speak with him.  Finally Martin forgives him and Clifford attends Martin and Sarah's (Mary Steenburgen) wedding.  The movie ends with Father Clifford using his story to convince the boy at the orphanage not to run away.
