Manager Chris Roe said the "gentle giant" died listening to the score of one of his favourite films, The Quiet Man, with his wife Suzanne and their daughter Tina.
Romero - the writer and director behind the cult-classic horror flick "Night of the Living Dead" - died Sunday.
"George Romero was a gentle giant, and one of the kindest and most giving human beings I've ever know or had the pleasure to work with", Roe told NPR.
Musician and director Rob Zombie, who directed the films House of 1000 Corpses, The Devil's Rejects and 2007's Halloween remake, also posted a tribute to the "zombie master". (SOUNDBITE) (English) FILM DIRECTOR, GEORGE A. ROMERO SAYING: "But its awesome that this is a film I made over 40 years ago and I just can't believe that the new edition is out here now, so long later". He will certainly be missed.
Romero's films were subversive, satirical, and sharply aware of the political climate he lived in.

Night of the Living Dead, along with being a classic film, reinvented the zombie genre, handing down rules about the undead that would stick for decades. The film was seen by some scholars as a subversive criticism of USA society in the 1960s, and has been added by the Library of Congress to the National Film Registry for works that are "culturally, historically, or aesthetically significant". He also directed such films as The Crazies (1973), Martin (1978) and the Stephen King adaptation Creepshow (1982).
Romero's magnum opus was Night of the Living Dead, the micro-budget film influenced by Richard Matheson's novel I Am Legend.
"I always used the zombie as a character for satire or a political criticism, and I find that missing in what's happening now".
Romero was born in 1940 in NY to a Cuban father and Lithuanian-American mother.
