Answer: Deep Roy
There are only two actors the world over who have achieved the sci-fi trifecta of appearing in the three biggest sci-fi franchises on Earth: Star Trek, Star Wars, and Doctor Who. The first actor to accomplish the trifecta was Deep Roy, best known to modern moviegoers as the face of the Oompa-Loompas in Tim Burton’s 2005 Charlie and the Chocolate Factory reboot of the Willy Wonka franchise (Simon Pegg is the second actor to accomplish the feat).
He appeared first in Doctor Who, playing Mr. Sin in the 1977 story arc “The Talons of Weng-Chiang”. He then appeared in 1983’s Star Wars: Episode VI – Return of the Jedi as Droopy McCool, an R2-D2 body double, and as an Ewok. Finally, he sealed the trifecta with his 2009, 2013, and 2016 Star Trek appearances as Keenser.
In addition to his roles within the three mega franchises, Deep Roy has also appeared in other sci-fi movies and television shows such as The X-Files, Planet of the Apes, and Flash Gordon.
