Ok Ive been searching for this movie title for 4 hours. The movie is in color and i think its set in Malibu Ca.Its a Comedy. A whole bunch of people end up in this house on the cliffs above the ocean during a heavy rain storm and get trapped in inside the house as it starts to slide down the cliff. In the end the house acually fips upside down and slides down the hill and on beach. i think it was late 60s or early 70s.
