(Either of two answers is acceptable.) Steve Martin was in just one John Hughes film but John Candy was in six. Three of those six also included the star of the movie described in question 2. One of those three obviously is the movie from question 2. Name either of the other two movies - a 1989 film in which Candy plays the title character, and a 1991 film in which Candy plays officer Danny Muldoon.
