The Arrival is a 1996 science fiction film directed by David Twohy and starring Charlie Sheen, and co-starring Lindsay Crouse, Richard Schiff, Ron Silver, and Teri Polo. Sheen stars as radio astronomer Zane Zaminski who discovers evidence of intelligent alien life and quickly gets thrown into the middle of a conspiracy that turns his life upside down.
The Arrival is reminiscent of The Invaders TV series that aired in the late 1960s, and is believed by some to have inspired it. A similar TV show, First Wave has similar plot elements, and may too have been inspired by The Invaders.
This film has a sequel called The Second Arrival.
