The new outfit/sonic screwdriver for McGann was done specifically for a New Zealand(?) fan convention, and isn't authorized by either the BBC or Big Finish (though BF did, finally, release an audio that has a new image of McGann instead of recycling the TV movie promo stills yet again).
I do like the new costume, though. It's a good bridge between his weird Edwardian thing from the TV movie and Eccleston's "U-Boat Captain" look.
