James Arness (1923–2011) is best known for his legendary portrayal of Marshal Matt Dillon in the classic Western TV series Gunsmoke, which aired from 1955 to 1975. Spanning an impressive 20 seasons, the show is widely regarded as one of the greatest Westerns ever produced, cementing Arness’s role as one of television’s most iconic characters.

Peter Graves (1926–2010), the younger brother, gained fame as Jim Phelps, the charismatic leader of the Impossible Missions Force (IMF) in the original Mission: Impossible TV series, which ran from 1966 to 1973. Like James, Peter enjoyed a successful career spanning decades, appearing in numerous TV series and films, including the hilarious Airplane! movies, where he playfully spoofed his serious on-screen persona. His distinctive voice and dependable acting made him a beloved figure in Hollywood for years.
Sadly, both brothers passed away in the 2000s—James in 2011 and Peter in 2010—but their legendary roles continue to inspire fans globally.
