Your yeast is having a party. It's doing just what it's suppose to do so you don't want to prevent it. No one ever said that fermentation was pretty!

i had this happen once and i thought it was an infection. i went ahead and bottled it and found that most bottles had the same film at the bottle neck. two weeks later, it had settled out and the beer tasted great. i don't know what it was, maybe yeast residue of some sort, but it went away and the beer turned out fine.

Ale yeasts are top fermenting, most beers will give you that film, sometimes even after the krausen dies down.
