LOS ANGELES—Saying that he’s going for a certain look and will know it when he sees it, feature film director Peter Hastings, 52, confirmed to reporters Wednesday that he hopes to find a relatively unknown actress for his next extramarital affair. “I’m definitely looking for someone fairly new to Hollywood, a face that isn’t already too familiar,” said Hastings, who noted that going with an ingénue in her early 20s over a better-established actress could provide just the kind of novelty he has in mind.
