Singin' in the Rain

[Don Lockwood (Gene Kelly) was insulted earlier by Kathy Sullivan (Debbie Reynolds) about being a movie star.  Kathy claimed that she was a stage actor, which in her mind and her argument earlier was more noble than movie stars. Now we get to see Kathy's profession.]

As is explained above Kathy, had expressed that movie actors were not real actors, that theirs was not a noble profession.  So Don then had asked what Kathy was and she said a stage actress.  Don jokingly talked about the greats of Shakespeare and the like. 

So Don sees Kathy in her profession which he wants to rub in, and yet at the same time it is all in good fun.  Don is not being condensing, but simply reminding Kathy of her unjust treatment of Don.  It is really rather fitting that Kathy is exposed like this.  We need to be reminded of the cliche "people in glass houses should not throw rocks." Kathy was demeaning Don's profession when she really knew nothing of what he had done to get his job, and the hard work involved.  Kathy got served a case of humble pie (pun intended).  

Often times we ourselves talk about things we are not fully acquainted with which leads to us putting our foot in our mouth.  We should not presume to think that any profession is somehow more noble, or worthy than anybody else's.  I should not look down on others simply because they apply a trade that is easy for me, or that I think is rather stupid.  We should reserve our judgment into all the facts are in, and make sure that we are not being hypocritical as Kathy was.   Not to mention we are all one body, though many parts.  I need the hand just as much as my foot, or eye.  Granted some parts are critical, but each provide the wholeness of society.  

Even though he had been made fun of earlier by Kathy, Don still treats Kathy kindly.  His compliment about Kathy being great was heartfelt.  He really did mean what he said, and she was an amazing dancer, and signer as we will see later in the film.
