What if 'Ghostbusters' was made in 1954?

A clever video editor has made a fake movie trailer that imagines what the 1984 movie "Ghostbusters" would have been like if it were made in 1954.
Replacing Bill Murray, Dan Aykroyd and Harold Ramis as Ghostbusters are Bob Hope, Dean Martin and Fred MacMurray, respectively.
Video clips used in the fake trailer come from such films as "Scared Stiff", "Ghost Breakers", "Topper Takes a Trip", "The Ghost Busters", "Abbott and Costello Meet the Invisible Man", "Ghosts on the Loose", "Spooks Run Wild", and "Flubber".
