Middle-class husband loses job and convinces his wife they need to leave the big city and start a simpler life elsewhere — that’s Lost in America. Middle-class people are thrown for a loop by hippie manners and appetites (like hallucinogen-taking) — that’s the last act of Flirting With Disaster. Throw those together and remove the exceptional, whip-smart writing and you’ve almost certainly got Wanderlust, a Paul Rudd-Jennifer Aniston comedy due in February.
