Peter Sellers in Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb.The remake of All Quiet On The Western Front wasn't a patch on the original 1930 film. The same with The Secret Life Of Walter Mitty in 1947. Nowadays you don't get actors playing several roles in the same film, e.g. Alec Guinness in Kind Hearts And Coronets, or Alistair Sim in the St Trinians comedies.
