I know he has been in dozens of movies and shows but he will always be Odo to me. Amazing how he could express himself in a mask that was designed to lack expression.
I am glad I had a chance to see him at the 50th anniversary convention in New York a few years ago. RIP.
I’ll remember him as Odo first, but he was also memorable as Clayton Endicott III on Benson.
He did a lot of Shakespeare in his younger days. His Edgar in King Lear was the one I’ve always remembered, above other Edgars.
I saw him in person in a Ralph’s grocery store in Pacific Palisades, years ago (the friend I was visiting pointed him out). I didn’t speak to him or notice what he was buying so it’s a pretty boring story–but it’s stuck with me over the years for some reason.
First Big Bird, then Odo…this has been one shitty day.
I wasn’t a huge watcher of the series, but I’ve always liked the one where Benson’s mother passed away, because it shows off Robert Guillaume’s talents so well. But Clayton gave us some much needed comic relief in that episode in a scene where he mistook the undertaker for the tailor who was supposed to come to measure him for a suit. Clayton’s reaction when he found out who the man really was (after the two talking past each other for a minute or so) was just priceless.
Nooooooooooooooo! 
Loved him in Benson and Star Trek: Deep Space Nine.
An Altman regular, he was the first Father Mulcahy and also appeared in the 6th Star Trek film as a different character before becoming Odo. RIP.
I first noticed him in a 1971 TV movie called “Escape of the Birdmen”. RIP.
I loved him as Odo and Father Mulcahey. Also, as the proud bearer of a French surname, I’m glad he never changed his floridly French name.
I loved him as Clayton in Benson, and was excited to see him in anything else like Warehouse 13. What a wonderful comedic character actor.
A tangentially related note, Marina Sirtis’s husband died too.
I loved him as Odo. This has been a bad year for fans of Deep Space Nine. Aron Eisenberg, who played Nog, passed away in September.
Yes, and D. C. Fontana earlier this week. In addition to helping get the franchise off the ground, she wrote the DS9 episode “Dax”.
Odo has shape shifted into dust. His bucket must be close by.
Rene was a very skilled actor to make that character work.
His best performance has to be the torture scene with Garak. Odo can’t change shape and it’s tearing him apart.
And Robert Walker.
Nog dead too…
Checking his Wikipedia article, I discovered that he’s a direct descendant of Joachim Murat, Marshall of France and King of Naples, and a several g-great-nephew of Napoleon. I did not know that.
Yes, a sad day for this die-hard **DS9 **fan. I’ll point out that he also had a memorable guest shot on *Frasier *as Frasier’s mentor, who turns out to not be quite what Frasier thought he was.
MAJ MARGARET “HOT LIPS” HOULIHAN: (Complaining about CPT BF “Hawkeye” Pierce) How did a man like that rise to a position of responsibility in the United States Army?!?
FR FRANCIS MULCAHY: (Looking up from his rosary) He was drafted.
RIP, Rene.
This is where I also first remember him. The song from the movie, Die Gedanken sind frei, played in another version on a music tape in my high school typing class.
