After Elmer Fudd debuted in the late 1930s, the folks at Looney Tunes decided to make the character look more like the voice actor who voiced him, Arthur Q. Bryan. As a result, the character is much more obese and unattractive. After a few films like this, the studio decided the retooled Elmer was a bad idea and returned to the more familiar version we are used to today.
This cartoon finds Elmer in the desert prospecting for gold. Not surprisingly, Bugs arrives mostly just to annoy him...and delight the audience.
There are several refences to the war (such as war bond posters and the lyrics to the song Elmer sings) but otherwise this is a timeless sort of film...enjoyable and full of the antics we all love.
