Using IMDB

I was also surprised when I found out that was Chris Hemsworth in Star Trek.

One of my favorite Apps. I use it for everything.

Yeah apparently Julianna Hough was an uncredited Hogwarts student in one of the movies. I can't remember which, I think its 1st or 2nd

ALWAYS USE IMDB

I use it to check reviews on episodes of a series to see if there are any really bad episodes I'd rather just skip.
