The actor John Heard, best known for his role in the Home Alone films, has died at the age of 71.

Heard was found dead on Friday in his hotel room in Palo Alto, California, according to celebrity news website TMZ.

The Santa Clara medical examiner's office confirmed the death. The cause is unknown.

Heard had reportedly been staying at the hotel after "minor back surgery" this week.

He went on to play leading roles in films including Cutter's WayC.H.U.D and Gladiator, opposite Cuba Gooding, Jr.

In 1999 he was nominated for an Emmy Award for his role as Vin Makazian - a corrupt New Jersey police detective - in television series The Sopranos.
