I first saw Animal Crackers when I was seven. When Groucho broke into his "strange interlude" and talked directly to the audience, it was as scary as if he had walked right out of the TV. This was a character that could break the rules of movies. And his rambling, pseudo-serious gibberish was a shock as well.
"Hideous, stumbling footsteps creaking along the misty corridors of time"
It sounded like he was being possesed by an evil (and boring) spirit. Needless to say, I was much more comfortable when "Normal Groucho" came back. For me, this is the weirdest thing in any Marx Brothers picture.
Hey, my mother tells me that the opening of THE HONEYMOONERS used to drive me to tears and into her lap. Apparently, I was frightened by the image of Jackie Gleason as the man in the moon!
For someone without a firm grip on reality, this can be a terrifying movie. Or even for someone without a firm grip on our culture. From the very beginning when everyone is expecting Capt. Spaulding's arrival with such excitement and he tries to escape like a total sociopath. To the entrance of Harpo when he loses his clothes and starts shooting into the crowd. His constant girl chasing. The strange interludes. And finally the mass gassing at the end. Most of the puns have to do with three characters who do not entirely understand the manners of their environment, nor the language, facial expressions, or vocal inflections. Yikes!
But the reality is that the Brothers were masters of these social ingredients, understood them fully and played with mistakes common to those around them like the mispronunciation of words, for example when Capt. Spaulding pronounces "fragile" as "fragilly", or Chandler mixing his name up with Spaulding's.
They reflected the flaws they saw in the people around them, but they did so in a charismatically humorous way. Bravo!
The basis of this scene actually gave Groucho the opposite of nightmares for years. This parody of Eugene Oneils Strange Interlude quotes the stock market crash of 1929,in which he lost most of his money,causing insomnia which plagued him for the rest of his life.
