This cast is perfect if you have seen them in certain movies & tv shows!
Hardly....
First off, Sonya Gomez, Kieran Duffy, and Fabian Stevens all appeared on episodes of
Star Trek, so your casting choices are really off, seeing as how Lycia Naff, Charley Lang, and Jay Baker have already played the roles.
Even if they weren't, Sanchez
might work as Gomez -- but it's a big "might" -- but McConaughey is all wrong for Duffy. (Levi as Stevens, I could maybe see.)
As for some of your other choices...
While I like Scott Lawrence, he's completely wrong for Tev.
As wrong as Lawrence is for Tev, it's as nothing compared to how wrong Ryan Kwanten is for Vinx.
And as wrong as Kwanten is for Vinx, it's as nothing compared to how totally thoroughly utterly totally completely inconceivably wrong Penn Jillette is for Bart Faulwell (though you could make an argument for his partner Teller). Jillette at best would top the list of "actors least appropriate to play Bart Faulwell."
Having said that, I have no issues with McKellan, Hargitay, Weisman (he'd make a really good Bynar, actually), Wong, Alonso, Smith, Common, Lesure, or Walton. I don't know enough about "The Glamazon" or Cigliuti, though the latter is the right physical type for Conlon.
