I Can't Seem To Say This Often Enough

'CASTED' IS NOT A WORD.

Cast is already past tense. You don't need to add the "ed." No, you really don't. I promise. 

You can say, "I got cast in the play." You can say, "they just cast a new actress to play Pansy Parkinson." But if you used the word "casted," I'm going to have to kill you.
