Mario Milita was an esteemed Italian actor and voice actor, born on June 26, 1923, in Cori, Italy, and passing away on August 22, 2017, in Rome. His career in the performing arts was exceptionally long, spanning over 65 years from 1946 until his retirement in 2012. During this time, he was active in theatre, film, television, and radio, but he became most renowned among audiences for his extensive work in dubbing animated content. His voice was characteristically coarse and raspy, a quality that made him the ideal choice for voicing elderly characters across cartoons, movies, and other entertainment media.

Milita's most iconic and long-standing role was providing the official Italian voice of Abraham Grampa Simpson in the animated series The Simpsons. He voiced the character from 1991 until his retirement in 2012, covering the first 22 seasons, and also lent his voice to the role in The Simpsons Movie. He was also the first Italian voice for the character Herbert from Family Guy and dubbed Fred Flintstone in various productions related to The Flintstones for many years.

Beyond these famous roles, Milita's dubbing portfolio in animation was vast and varied. He voiced Grandpa Lou Pickles in the Rugrats film series, Mumm-Ra in ThunderCats, Gennai in Digimon Adventure, Laughing Bull in Cowboy Bebop, and the narrator and Doctor Harada in Captain Tsubasa. In the first Italian dub of South Park, he provided voices for Marvin Marsh and Harold Cartman. He also voiced characters in animated films such as The Hunchback of Notre Dame, Hercules, and Lady and the Tramp II: Scamp's Adventure. The specific roles mentioned in the query—Babbo Natale in Mori no Tonto-tachi, Inspector in The Brave Frog, and Urobe in Vicke the Little Viking—could not be confirmed in the available sources.

In addition to his animation work, Milita was a prolific dubbing artist for live-action films and television series. He frequently dubbed the voices of actors such as Desmond Llewelyn (as Q in the James Bond films Moonraker and A View to a Kill), Ed Williams, and Brian Doyle-Murray. Other notable dubbing credits include Old Man Peabody in Back to the Future, Amos Tupper in several episodes of Murder, She Wrote, and roles in films like Home Alone, Rocky, and Rocky V.

Throughout his career, Milita's contributions to the art of dubbing were recognized. In 2008, he was awarded a prize for his career achievements at the Gran Premio Internazionale del Doppiaggio. His voice began to weaken around 2004, becoming more feeble in his later years of activity, which led to his retirement in 2012. Upon his retirement, the roles of Grampa Simpson and Herbert were passed on to other voice actors. Mario Milita passed away in Rome on August 22, 2017, at the age of 94.
