Chris, I didn't mean to suggest that you start drinking coffee black or with skim milk. I just thought that, as a one-time experiment, it would be helpful to see if the film formed in the absence of the fat from the half-and-half. That would indicate whether the oil came from the coffee or the half-and-half.
Try a lower fat content cream, and see if there is still oil on the surface. My wife is a tea drinker and uses 10% (ugghh) so the fats stratify on the surface if left too long. There are oils in coffee but I dont think they would cut through the cream, unless you are using a connoisseur ratio in your coffee brew.
I use 2% in my coffee and that's it. No sugar. One day I will drink it black, but I don't get any oils on the surface if I leave it.
This ia an oily beverage you're drinking, OK. When you take your freshly roasted beans and pour them on a plate to cool them off the plate gets rather slippery with all the oils, especially if you've roasted the beans hard and they have gotten shiny.
Cherish the oils, the film or whatever you wanna call it.
I mean, how does it taste? Is the film disgusting to you cause it looks bad or becuase you actually get a taste you don't want?

Here is a picture, its hard to see (sorry only had a camera phone to take the picture). Its hard to notice but on the top right of the picture the "film" is developing, it also stuck to the cup as a clump..... shocking I know.
Ewwwww! The oils from the coffee should not do that. If you drink black coffee, you will notice oily spots or swirls on top of the liquid. Clumps are not good. That sounds like the milk solids are separating (butter/curdling) and that is not good eats. Coffee that requires a spoon and chewing is, well, grouse. Try a different percentage milk fat cream from a different manufacturer.
