I'm with you all around. More Who is always welcome, especially given the short shrift the 8th Doc was given. It seems like a waste to have him just laying around, especially when McGann is still young enough to play the part.
Still, the idea of putting out a movie feature a completely different Doctor won't work in this day and age when branding is such a big deal, more so than it was in Hartnell's and Cushing's day.
