Okay, here’s an odd phenomenon. In some film series (or just a film and its sequel), they will have mostly the same principal actors, it’s in the same continuum, but there’s an actor or actress in two different installments playing a different character. Here are some obvious examples, give me some better ones:
Stan Lee, who plays slightly different characters in most of the Marvel Comics movies. In Captain America: The First Avenger, he’s a general, but in Winter Soldier he’s a Smithsonian rent-a-cop.
Sofia Coppola plays the infant Michael being baptized in The Godfather. In Part Two she’s an immigrant kid on a boat. In Part Three she’s Mary Corleone, one of the primaries.
Maud Adams has been in three James Bond movies, all starring Roger Moore: She’s Andrea, the beta Bond Girl in The Man with the Golden Gun; Octopussy in Octopussy; and she has an uncredited bit part in A View to a Kill.
I’m excluding TV shows, although there’s a proud tradition of this on the small screen as well.
Who are some others?
