"The planet is dying, and you can believe it because I'm Michael
   Caine" I just read that in a very acidic review of Interstellar
   [which I want-to-see/still-haven't] and the critic was a bully.
   At the same time, it's true: If Michael Caine says something in
   a movie, it's simply a fact.* Morgan Freeman has that very same
   power.
