David O. Russell used his own experiences to add realism to “Flirting With Disaster” 

Writer-director David O. Russell looks a lot like Ben Stiller, who stars in Russell’s latest picture,  “Flirting With Disaster.”  The  physical similarity hasn’t been lost on the director of the critically acclaimed “Spanking the Monkey.” “I wouldn’t say that that’s why Ben got the part,” Russell said earlier this month during a lunch interview at the Ritz-Carlton Hotel downtown.  “But yes, it’s come to my attention that there is a likeness between the two of us.”
