I'd love to see David Tennant as the captain, but being as that he was already Dr who, and just being as awesome as he is in general, I fear adding the captains chair to his resume would make it so that science fiction fans would LEGALLY have to worship him as our new messiah. Personally? I'd love to see Christian slater in the role. He seems perfect for it, and is a huge trekkie in real life. He would make a dashing captain Imo.
