Hollywood's Hidden Lives (2001)

"Don't tell... it's our secret."

Frank and Stephanie are rich Hollywood producers, so bored with their contemporary relationship that they take to spying on their guests via high-tech surveillance equipment. David and Madeline, on the other hand, are still struggling for their first big breaks. He's a screenwriter and she's an actress, which comes in handy when it comes to convincing Frank and Stephanie to let them use their guesthouse. You see, their relationship is entirely fictitious - designed to help them find decent accommodations while honing their crafts. The truth is they really can't stand each other.
