They sent me a PDF with a bit of backstory on all the characters, Wesley tells EW.

Then, honestly, I went on the Wikipedia page and looked at that.

I dont know their mannerisms and I dont really know any of these cast members very well.

I was sick, Wesley says.

I had like a 103-degree fever while I was shooting all those exterior scenes.
