There are a few different versions of this film. The basic one is the pig makes advances on the girl, she pulls off his jacket, and mostly they dance. The one I like is the longer version, with a closeup of pig wagging his tongue, wiggling his nose, and flopping his ears. Great pig. 3.5 stars.
The pig keeps dancing till it's no longer a pig but something else. At first nicely dressed in tuxedo, the pig is a symbol of wealth &privilege. The floozy strips away his status, his identity; debases him, forces him to wear drag; objectifies him the way the pig had objectified her. It's all a silly little routine performed in wide shot, but it gets at something about class & gender identity that's almost satirical.
If you ever wonder where the magic of geniuses like Frank Oz and Jim Henson came, this piece is an important part in the development history of puppetry. Single without pure than those yesterdays entertaining pretensions. 4 minutes completely worth it.
6 - The first couple of minutes (i.e. most of the film) are bizarre, but quite charming in their own way. The short close-up on the pig at the end is creepy as hell, almost like the thing is having a stroke. It's all completely harmless if you have a tolerance for nightmarish pig masks. I guess you also could extract some commentary on gender roles out of this, but I really doubt that was the intention behind it.
