Pre-Hysterical Hare

Pre-Hysterical Hare is an infamous Looney Tunes cartoon starring Bugs Bunny and Elmer Fudd, directed by Robert McKimson, and released on November 1, 1958.

Plot
Bugs Bunny shows a film about a caveman Elmer Fudd attempting to hunt a primitive rabbit.

Why people call it Looney Trash
People call it Looney Trash because it's boring, as it goes at at a very slow and lazy pace, which completely kills the comedic timing.

The short reuses animation from "Caveman Inki" in one scene, which doesn't blend in well with the rest of the original animation.

It has the same concept as an earlier Looney Tunes cartoon "Prehistoric Porky", but was poorly executed and has weaker jokes unlike "Prehistoric Porky", which had much funnier jokes and was more fast-paced and charming.

Due to a musicians' strike, this was one of the few shorts that use stock music from Capitol Records rather than music by Carl W. Stalling or Milt Franklyn. The Capitol music isn't as good as Stalling or Franklyn's music, and can rival those of Lava's music in the 1960's shorts. It's made worse by poor choices of music, as other cartoons from the musicians' strike period (including the Wile E. Coyote and Road-Runner cartoons "Hook, Line and Stinker" and "Hip-Hip Hurry!") still worked reasonably well with the Capitol music. Here, they seem to have chosen the blandest, most forgettable tracks in Capitol's entire library, and a lot of music choices are ill-fitting.
