um, isn't star trek the property of paramount? hasn't he just had a BIG falling out with them? will he offer to pay them for the privilege of appearing? he doesn't strike me the sort of person to apologise and approach paramount cap in hand.
This was probably said as a joke by TC because of the fall-out with Paramount - wouldn't be surprised if Abrams, being his pal, doesn't sneak him in as a Klingon in the background or some such malarky just for a laugh.
The one single thing the Tomster did that I liked was the cameo in the Austin Powers opener. Apart from that - bleeurgh, step AWAY from the Star Trek set now Tommy lad and get back to nappy changing - there must be something you are good at.
I was (almost) supportive of TC earlier in the thread, when he was originally suggested for a cameo but now with the prospect of him being Spock??? This is a most illogical choice.
