Behind the scenes
- Scrooge McDuck is a fictional Disney character who first appeared in various comic books from 1947 before going on to appear in other media. He is the in-universe uncle of Donald Duck (from the same fictional universe as Mickey Mouse). The character is known for, among other things, his immense wealth.
- David Tennant voiced Scrooge in the 2017 revival of the animated series DuckTales. Prior to this, one of the most renowned authors of comics featured Scrooge, American cartoonist Keno Don Rosa and self-confessed fan of Doctor Who, had drawn a rendition of Scrooge (in a costume reminiscent of the Eleventh Doctor's) using the TARDIS to go back in time to 1896 in the Klondike, meeting his younger self just as he is about to become a millionaire[1], and another one where Scrooge (in his normal costume) appears intent on selling the TARDIS at a "Slightly Used Tardis Lot"[2]. Both cartoons are considered canon on the Scrooge McDuck Wiki, though not (obviously) on Tardis Data Core.
