Doctor Who vs. The Outer Limits

Doctor Who aired an episode called Smith and Jones back in 2007 where:

"The episode sees the Doctor (David Tennant) meeting Martha Jones (Freema Agyeman), a medical student at Royal Hope Hospital. The hospital is transported to the Moon, whereupon the Doctor and Martha must contend with a Plasmavore posing as Florence Finnegan (Anne Reid), as well as the Judoon (voiced by Nicholas Briggs), who are hunting for Finnegan."


Which always seemed familiar to me somehow until I recently ran across this:


A Feasibility Study an episode of The Outer Limits from 1964 in which:


"Residents in a city suburb awake one morning to find their neighborhood has been transported to another planet the previous night. The intention of the aliens is to study the feasibility of enslaving the entire human race to do manual labor on their planet. But the aliens must overcome humanity's susceptibility to its diseases, and the willpower of mankind's resistance to slavery."


While not exactly alike, it's similar enough that the Doctor Who episode seemed familiar to me.
