Cliff Simon was not just a fan-favorite at conventions, who played one of the Stargate universe’s most beloved baddies, Lord Baal. The actor was also loved by his co-stars.
With the news of Cliff’s passing in a tragic kiteboarding accident earlier this week, his fans and coworkers alike have been pouring out their love, their memories, and their grief online. Here we’d like to showcase some of these words of kindness, as the worldwide Stargate family continues to grieve together.

Many of the actors below never appeared on screen with Cliff. Instead they got to know him on the convention circuit, and as a fellow member of the Vancouver and Los Angeles television guilds.
Below is a sampling of some of the outpouring of love and affection on social media this week. Meanwhile we hope you’ll share your favorite memories of Cliff in the comments below (or tag @GateWorld on Twitter).
And please join us this Sunday on the “Dial the Gate” YouTube channel (March 17 at 12pm Pacific time) for a livestream memorial and celebration of our friend Cliff Simon. We’ll be sharing our memories of Cliff and his stellar performances as Baal, and opening up space for other fans to share as well.
So incredibly sad to hear of @cliffmsimon passing away. What a wonderfully lovely man he was. Such an important part of the Stargate family. I’m speechless. RIP ?

I planned to share some photos today of the beautiful vibrant spirit that is Cliff Simon, but…another time. Love you, Cliff. How is it possible to feel so close and connected to someone you only get to see now and then? When someone is the embodiment of life itself, it’s easy?

Been a couple days of deep reflection. @clifffmsimon had professional families who grieve with his closest loved ones. He was a Superman and a super man. There'll be more remembrances as this sinks in. His passing has rocked the #Stargate world. We love him and won't forget. ? pic.twitter.com/H8ev3fd4og

We comprised a unique group of sci-fi baddies over the #Stargate years. @cliffmsimon @SuanneBraun with South African roots, @JSamuda and I with Jamaican roots.
That's a powerful axis, and the balance was a thing of beauty. #onelove #RIPCliffSimon ???? https://t.co/4nis7U7KMu— Peter Williams (@actualApophis) March 12, 2021
I don’t have any photos with Cliff Simon. But I remember him fondly. He had the most insane stories, and he would weave them masterfully. I sat enthralled – listening, laughing… I remember every car ride, brother.
Hope you’re holding court somewhere interesting.

So sad,I just watched SG1 with my 10 year old son,just finished the last episode a week ago. My son loved his character to in the show.i watched sg1 maybe 15 times and loved how he played the roll of Lord Ba’al.
❤Rest in peace ❤
He was one of those actors i can’t forget in SG franchise. I never had the opportunity to meet him at conventions, and i regret it deeply. Just a few episodes with him were more fun because of him, and the Stargate Continuum movie was more fun because of him. Based on crew co-stars reactions, he was truly a nice guy. Gone too soon.
I will miss him.
