Monster in the Garage (1997)

Poor Steve. He's a slob and everyone gives him a hard time about it. He and his lovely wife, Edie, are planning a party at their house this evening. Little do they know that a flying saucer from another world has crash landed in the field behind their house. Not only that, but the hungry creature from inside the ship has escaped and is hiding in their cluttered garage. As guests arrive for the party, some will make their way to the garage...and may never be seen again!
