4. Jemaine Clement (as the Goblin King)
This one is kinda just for fun. Many folks my age chiefly identify Bowie as the codpiece-sporting Jareth from the Jim Henson film Labyrinth. Bowie was not merely a musician who appeared in film. He was an actor, in the greatest sense. He was so talented as an actor that he could have quit music and focused solely on movies. Thank goodness he didn't, but still.
Clement, meanwhile, has had a similar symbiotic relationship between his oddball musicianship and his captivating work on camera in both "Flight of the Conchords" and some other crazy projects like the vampire mockumentary What We Do In The Shadows. He's also a big enough Bowie fan to write and perform his spin on the "spaceman" era. We could have a lot of fun with a vignette of Clement as Bowie, suiting up to act opposite some muppets dressed as a weird subterranean sex-lord-thing.
