In a post to a_film_by on August 2003, Tag Gallagher, talking about Howard Hawks, asked: "Is sanity truly a goal or even a desideratum in Bringing Up Baby, The Big Sky, Red River... ?"
And in another post, the same day:
"I'm not sure that people are trying to cling to sanity, but I suspect that sanity is an illusion in Hawks, and that biology rules all, and from a male point of view (Hawks's) that's the power of women. Sanity may be a possibility, but it's irrelevant ultimately."
I think these statements go to the very heart of Monkey Business, which I saw countless times by now.
Here is a dialogue from the film:
Barnaby: Hello, Griffith Park Zoo, Snake Department. Sssshhh!
Oliver Oxley: Hello? Hello? What is this?
Barnaby: What do you want?
Oliver Oxley: This is Mr Oxley.
Barnaby: I'll see if he's here.
Oliver Oxley: No, I said *this* is Oxley!
Barnaby: Who is?
Oliver Oxley: I am, speaking!
Barnaby: Oh, you're Mr. Speaking...
Oliver Oxley: This is Mr. Oxley speaking!
Barnaby: Oxley Speaking? Any relation to Oxley?
Oliver Oxley: Barnaby Fulton is that you?
Barnaby: Who's calling?
Oliver Oxley: I am, Barnaby!
Barnaby: Oh, no, you're not Barnaby. I am Barnaby! I ought to know who I am.
Oliver Oxley: This is Oxley speaking, Barnaby!
Barnaby: No, that's ridiculous! You can't be all three. Figure out which one you are and call me back!
Not only it is one of the funniest films ever made, it also has THE most romantic kiss scene ever (the first one, when they're staying home from the Everett Winston party).
