The Prince of Tides has washed up in rehab.

Nick Nolte, last seen looking a tad disheveled in a police mugshot for a DUI arrest, is in a Connecticut treatment facility, the actor's camp announced today.

The two-time Oscar nominee "voluntarily entered Silver Hill Hospital to receive advice and counsel that he feels he needs at this time," publicist Paul Bloch said in a statement.

There's no timetable for Nolte's release. "He will be there as long as he feels is necessary," Bloch said.

According to the rep, Nolte checked himself into Silver Hill on September 14. That was just three days after the 61-year-old actor's headline-making arrest in Malibu, California.

Nolte was behind the wheel of his black 1992 Mercedes-Benz when, according to the California Highway Patrol, he was spotted having difficulty keeping the luxury car in a lane--any lane--of the famed Pacific Coast Highway. Nolte's Mercedes weaved "across all south-bound lanes and into the opposing lanes of traffic," the CHP said.

Nolte subsequently was pulled over, and, per the arresting officer, found to be drooling and disheveled. While no drool present in Nolte's resulting mugshot, the pic, featuring the wild-haired actor sporting an even wilder Hawaiian shirt, did seem to convey the disheveled look.

Nolte, booked and released following the arrest, faces a possible misdemeanor charge of driving under the influence. A court hearing has been scheduled for October 28.

At Silver Hill, Nolte will be helped out by people who recently helped "Piano Man" Billy Joel.

Nolte has copped to being a heavy drinker in the past--although it was presumed the heavy-drinking days were in his past. The man once reprimanded by Katharine Hepburn for being a fall-down drunk (they costarred in 1984's Grace Quigley) said he cleaned up in 1990.

It was in the 1990s that Nolte's always-steady career began to receive new, serious notice. Nolte scored two Best Actor Oscar nominations, for 1991's Prince of Tides and 1998's Affliction, and starred in the hit 1991 remake of Cape Fear.

Of late, Nolte recently wrapped work on the Ang Lee-directed comic-book flick, The Hulk, in which he plays the incredible Bruce Banner's father, Dr. David Banner. The would-be blockbuster is due next summer.
