Things that are perfect:

1. Robert Guillaume as Leo. He basically played the Leo character on Sports Night, so it makes perfect sense.

2. Tamara Taylor as CJ Cregg. She is fabulous and possibly the ONLY thing I miss about Bones.

3. Enrique Murciano as Sam. OMG YOU FOUND AN ACTUAL LATINO ROB LOWE.

4. Irrfan Khan as Danny. When I ever get around to casting people to play my family, he's totally going to be my uncle.

5. Toby and Ainsley. I don't even know those actors, but they look perfect.

I also don't know the guy you cast as Bartlet, and that's kind of a crucial role, lol, but the ones that I do seem right on.

(Sidebar: You totally make me want to race and/or genderswap things! But I need ideas! lol)
