Alex Trebek was kind enough to film a cameo for our film Free Guy last year despite his battle. He was gracious and funny. In addition to being curious, stalwart, generous, reassuring and of course, Canadian. We love you, Alex. And always will.

Alex wasn’t just the best ever at what he did. He was also a lovely and deeply decent man, and I’m grateful for every minute I got to spend with him. pic.twitter.com/CdHCcbqmp2

I was obsessed with Jeopardy as a nerdy kid growing up in Ohio. I’ve loved and revered Alex Trebek since I can remember. What an iconic career. RIP Alex Trebek.

Couldn't we have one nice weekend? A kind gentleman whose excellence was so consistent, it was easy to take for granted. Rest well, Mr. Trebek. https://t.co/Zq7RN6kSKk
