You may have seen one or took one by mistake thinking it was the other "movie". If you don't know, The Asylum is a studio that make their own versions of the "big" movies of the year. They will put their own a spin on the story. Sometimes, they are not so bad. ;) Those are direct to DVD movies that cost a lot less than their counterparts(1 or 2 millions to make).
Here are some examples of upcoming movies:

I Am Legend = I am Omega (pre-production)
Transformers = Transmorphers (June 26, 2007)
The Invasion = Invasion of the Pod People (July 24, 2007)
Alien vs. Predator: AVP2 = Aliens vs Hunters (pre-production)

Earlier movies:

The Hitcher = The Hitchhiker
Pirates of the Caribbean: Dead Man's Chest = PIRATES OF TREASURE ISLAND
The Omen = 666: THE CHILD
War of the Worlds = H.G. Wells' War of the Worlds (with War of the Worlds: The Next Wave in pre-production)
