What Sci-Fi TV shows. movies or books contain the idea that aliens are living secretly among us?

wasn’t there a show named “V”?
I think that was the name.

Well, “Invasion” was the TV series that got cancelled after first season, a pretty good show though.

Men in Black….Men in Black II.

X-files

My favorite Martian, Mork and Mindy

The Adventures of Buckaroo Banzai Across the 8th Dimension

80s cult classic and an alien (pre 3rd Rock) John Lithgow gives a priceless performance.

My step mother is an alien. (movie) Superman series TV and movies

A great film of this genre from the late 80s: They Live.

THEY LIVE was the best of the suggestions.

Thanks to all who played!

didn’t realize it was a contest but oh well…“wherever you go…there you are.”
-B. Banzai (as played by Peter Weller)

Battlestar Galactica. The ‘aliens’ are actually artificial intelligence that has evolved. But they do live among humans without people knowing they are not human.

Battlestar Galactica is a must see!

There’s the short-lived animated series Invasion America.

K-PAX.

@ironhighway-right, KPAX was a good one-good message and spacey wasn’t half lame in it either…kaiser sosa!

Ah, man. Somebody beat me to the Rowdy Roddy Piper classic, They Live. Best line ever:

“I’ve come here to kick ass & chew bubble gum. And I’m all outta bubble gum…”

There’s always “Invasion of the Body Snatchers”, every other episode of “The Twilight Zone” and “The Outer Limits”, Alien Nation (Both the movie and tv series).

Dark City (in a way), The Astronaut’s Wife (kinda bad),
Taken(mini-series I think)

The “Witch Mountain” movies: Escape to Witch Mountain, Return from Witch Mountain, Race for Witch Mountain

Holy moly, they forgot #rd Rock From the Sun….... ;-)
