Aidan Quinn (photo) pleaded guilty to drunken driving while he was in Maine for the filming of the HBO movie “Empire Falls.” Quinn didn’t appear in Kennebec County Superior Court in Augusta on Thursday, where his plea was entered through his lawyer, Michaela Murphy. Quinn, 46, was ordered to pay a $500 fine, and his driver’s license was suspended for 90 days. Quinn, who lives in Englewood, N.J., was arrested by Waterville police on Oct. 25, 2003, after he was observed driving erratically. After he was pulled over, a test revealed his blood-alcohol content was 0.12 percent. The legal limit for drunken driving in Maine is 0.08 percent. “Empire Falls” is set to debut in a two-part series on HBO May 28-29.
