Deep Roy

Actor (Keenser) — Kelvin timeline films

Kenyan-born British actor and stunt performer who played Keenser, Montgomery Scott's small and largely silent alien assistant, in all three Kelvin timeline Star Trek films.

Deep Roy is a British actor, puppeteer and stunt performer, born in Nairobi in 1957. His long career includes Doctor Who, Return of the Jedi, The NeverEnding Story and several films for Tim Burton, most famously Charlie and the Chocolate Factory, in which he played every one of the Oompa-Loompas.
In Star Trek (2009) he plays Keenser, the diminutive alien who shares Scotty's exile at the Starfleet outpost on Delta Vega. The character joins the Enterprise engineering staff and returns in Star Trek Into Darkness and Star Trek Beyond, in the last of which his acidic sneeze helps the crew escape a locked compartment.
Keenser has almost no dialogue, so Roy's performance rests on movement and reaction beneath heavy prosthetic make-up.
