The mediocre horror flick "Bats" was released in a slightly censored version that received the PG rating. The PG version then was on the VHS, the later released DVD, however, contains the uncut R-Rated version. This uncut version was released in other countries as well.
Comparison between the cut PG-13 version taken from the US VHS by Columbia and the uncut US DVD by Columbia (R-Rated)
In the death scene at the beginning, some frames of the girl are missing. One can see her forehead bleeding.
Despite the fast cutting at this point some alternative footage has been used. The R-Rated version is longer and more explicit, however, this is barely noticeable. The still frames shown here are therefore much more brutal than in the movie itself.
PG-13: 0,4 sec.
R-Rated: 0,5 sec.
During the autopsy of the male corpse, some alternative footage hsa been used again. The PG features the scientist talking, the R-Rating shows the corpse instead and the text can be heard as voiceover.
No time difference
The deputy sheriff's death is a lot less cruel in the PG-13 version. Two shots of the deputy sheriff fidgeting on the ground are missing, blood is splashing on his face. The following shot lacks its beginning (close-up on the face) and is therefore rather harmless.
A shot showing the bat tearing a piece of the scientist's neck skin out is missing.
Another hectical shot of the scientist being eaten by the bats is missing, blood is splattering again.
The shot of the scientist with his ear eaten off was shortened by 4 frames.
