Who was the brother of actor James Arness?

I did not know that.

Peter Graves was hilarious in that classic flick Airplane!

I remember Peter Graves in a TV show I watched as a kid in the 50's: "Fury". My favorite character was Pete, played by William Fawcett, who was a rare bird in Hollywood with a PhD! Yet even with such pedigree, his most famous role was as a hillbilly in "No Time for Sergeants" playing Andy Griffith's paw at the beginning of the movie: "Print big!".

Wow! What a revelation.

I got it correct because I could see the resemblances. I didn’t know anything about either having a brother.

Aware they were brothers who acted in the same genre and never together, but not htat Graves directed an episode of Gunsmoke.

Bjach, if you closed your eyes & heard them speak their voices were identical.

Peter Graves was the best Jim Phelps. He was no traitor, unlike Jon Voight.

urtrippin2, Lloyd Bridges made it for me.

Tony, not John Wayne's brother. James Arness' brother.

How could James Arness be brothers with himself? Lol Really, I had no idea Peter Graves from Mission Impossible was the Duke's brother! Amazing the things we learn from this game.

No way!!! Nobody mentioned aboutPeter and James are brother.

WaldoLydeker, Mayim Bialik, who played Amy on the Big Bang Theory has a Phd in Neurology.

Interesting, I wasn’t aware of this either, but I I got it right cause I looked at the eyes, just felt they like Peter Graves.

Bjach, my older brother told me about years ago, but until I saw this photo of James, I never saw much of a resemblance.
