Interestingly, the BBC have restricted use of former incarnations of the Doctor in IDW-published comic books, apparently citing actor-likeness issues…
Reported by io9.com in their article concerning Tony Lee’s confirmation yesterday at the New York ComicCon that he is penning a new series of Doctor Who comics for IDW, this is an interesting stance to take from the BBC, and as yet it isn’t clear exactly which actor’s likeness has been called into questi
Meanwhile Tony Lee – the writer of IDW’s Doctor Who: The Forgotten series – has given the BBC "a massive six thousand word pitch" covering the new comic book series as well as reasons against using existing companions:
If you do a new Martha story everybody knows how it ends [but w]ith new companions, you can do things people don’t know.
…Tony Lee plans instead to pitch the Doctor into situations with existing famous historical characters, new villains, returning villains and at least one exciting new companion for the series currently set for a July launch.
