Rest in peace.

Really sad, he's associated with a lot of great stuff.

I knew he must have been in bad shape when he cancelled an appearance at Portland's annual HP Lovecraft festival.

Rip

That sucks. RIP.

Big fan. What a letdown.

RIP....until the acid rain.

Return of the Living Dead always fascinated me when I was younger. It was thrilling, scary, and always fun. First horror movie that I ever saw like that.

And, for some reason, Dan O'Bannon was one of the first names that stuck in my head, when I was ten-or-so, just watching and learning about movies.

RIP

I saw him speak at a screenwriting conference a few years ago in Los Angeles. Sad to hear of his passing.

I'll have to give the Alien supplements a spin this weekend.

Return of the Living Dead is one of my all-time favorites, and I love his segment in Heavy Metal.

RIP

Very sad news. I'll give ROTLD a spin this weekend.

That sucks. RIP

He made some great contributions to the world of horror. Sad to hear about this.

I'm pretty bummed right now. I woke up in a great mood (doesn't happen often haha) and literally the second thing I saw on the net was of his passing. As someone else said his name was one of the first I remembered when I was younger, and I've been a fan of his for 2/3 of my life. RIP

THIS JUST IN: O'Bannon isn't dead, though he appears to have major medical problems. I just received a message from him saying, "Send more paramedics."

Had the pleasure of meeting him at a Fangoria Weekend of Horrors, way back when that show was cool. Twenty years ago? The cast of Return of the Living Dead was there (signed my poster!), but I just talked to him. Mostly about Alien.

Well, OK, I talked to Linnea Quigley a lot, too.

Sad day. Too young!

I feel so embarrassed to admit that I didn't realize he was writer/director of Return of the Living Dead.

I am quite upset to hear that he passed away. I was always a huge fan of his work and like others here, he was one of the first people I was aware of when researching my favorite films as a kid.

Passing of a giant, and way too young. For a time there, every making-of doc I watched had him in it. I like the idea of him crawling out of the grave to eat our braaaiiiins, though.

Alien is one of my all time favorite films. He will be missed.

I've always enjoyed both Alien and Dark Star.

VERY sad news to me!!
R.I.P. Dan!!

thanks for everything...RIP
