I have had the Marx Brothers on my mind quite a bit lately, been watching several of the movies as well as having recently subscribed to the Marx Brothers Council podcast.
One thing I've been thinking about, that was discussed on the podcast at least, is that Chico Marx gets discussed and celebrated less than Groucho and Harpo. And I think I do care a bit more about Gummo and Zeppo more than Chico (should I be named Minor Marx?).
Gummo left the group while they were only performing on vaudeville, before they started film, so there's not really film or audio examples of his work, and Zeppo didn't get much to do in the movies he was in (I find myself wondering if he got any dialogue in Animal Crackers) and retired from the group after five films. But these facts do get me thinking more about them - what was Gummo like? What would life be like if Gummo and Zeppo appeared together on stage or in film? What if Zeppo did more in the films? Would he have eventually been a bigger part of the films if he remained part of the gang? And I've seen different theories on why Zeppo left.
I also wonder, should Harpo have eventually spoken? I know, he did talk when the group began performing, and there's some debate over whether he sang "Sweet Adeline" with the group in Monkey Business. Often in films when there's a character who's primarily silent, they tend to end up getting a word, maybe as a joke or the characters reacting in shock that they can talk, I wonder if Harpo should have gotten a line a film, maybe with some kind of gimmick (like starting to talk and getting interrupted after just a few words).
