LOS ANGELES Hollywood remains under attack from aliens.

Paramount Pictures is the latest studio to snatch up an aliens-related pitch, this one to be produced by Michael Bay.

Though the plotline is getting the Area 51 silent treatment, the project has been described as "Cloverfield" meets "Paranormal Activity." That would indicate one or more of the characters doing the actual street-level filming.

Bay, in particular, can't seem to get enough of the sci-fi genre. In addition to filming the third installment of the alien-robots-at-war "Transformers" franchise for Paramount, Bay is producing the aliens-in-high-school thriller "I Am Number Four" for DreamWorks Pictures.

That same studio is currently filming "Cowboys & Aliens" with director Jon Favreau at the helm.

Meanwhile, Sony Pictures has its aliens-attack-L.A. action movie "Battle: Los Angeles" on the books for a March release in the U.S. At the same time, Universal Pictures has the alien-abduction thriller "Skyline" scheduled for U.S. release in November.
