Mayhew, who stood 7-feet-3-inches tall, originated the role in the the original film in the franchise, Star Wars: Episode IV - A New Hope, released in 1977, and reprised the role in Star Wars: Episode V - The Empire Strikes Back (1980) and Star Wars: Episode VI - Return of the Jedi (1983).
In 2005, he once again donned the famed costume for Star Wars: Episode III - Revenge of the Sith, and returned for 2015's Star Wars: Episode VII - The Force Awakens. He also played the character in the oft-maligned cult classic The Star Wars Holiday Special in 1978.
Peter Mayhew’s son-in-law tells ET Peter died of a heart attack. Peter was with family when EMT’s arrived. The family asks that people consider donating to the Peter Mayhew Foundation, a non-profit organization devoted to the alleviation of disease, pain, suffering and financial toll brought on by life’s traumatic events.
Mayhew retired due to various health issues before production began on Star Wars: The Last Jedi, but served as a so-called "Chewbacca consultant" to help his successor, Joonas Suotamo, who had served as an understudy, of sorts, for Mayhew during filming on The Force Awakens.
He is survived by his wife, Angie, and their three children. According to the statement posted by his family, there will be a memorial service for friends and family held on June 29, and a memorial celebration for fans at the Star Wars convention Empire Con L.A. in December.
In lieu of flowers or gifts, the family has asked friends and fans to consider donating to the late star's charitable organization, the Peter Mayhew Foundation. Click here for more information and to donate.
