Lead characters are extremely important for TV series, as they are the basis of the shows' storylines. However, to make said lead characters shine and make the storylines interesting, supporting characters must be introduced. Sometimes, those characters have a major impact on a series and even end up becoming leads. Just see how Ben Linus on Lost was set to appear in a few episodes, but ended up being so helpful to the storyline and loved (or hated) by the fans that he became an integral part of the series and is now a major player on the show.

That compelled me to make a list of new supporting characters who helped make their series better this season. Since my list only has 10 items and because I don't watch all current TV series, I will have missed tons of supporting characters, so feel free to add to the list by commenting below. However, note that I restricted my list to supporting characters that were introduced THIS season. So the Ben Linuses of the TV world are not on the list.

...Nine foreign Americans

With all of the starry-eyed, out-of-work Midwesterners who litter Sunset Blvd., one would assume that our television landscape would be similarly populated with corn-fed blonds. You would, however, be wrong. In fact, there are a ton of non-Americans who have come to Hollywood to take all of our primetime show-starring jobs.

What's fun for me is watching the shows to see who does a good version of an American accent, and who needs to spend a little more time with their dialect coaches. Below are nine stars who've jumped the pond to come to the good ol' U. S. of A.
