I personally have extreme objections to RED DAWN, the first movie actually endorsed by the NRA. Not wanting to get into a debate on political correctness, I'll just say that it is crap on oh so many levels.
The rest of the list is at best shaky. Hopefully the 5 still to come will redeem it. The "Surprises" are often oldies of 50s or 60s vintage. I will be there.

Note that the FRAU IM MONDE, Fritz Lang epic, is probably the 95 minute US edited version rather than the longest version, 200 minutes.
I wish that I could say that I had seen the long version, but I missed my chance twice. Once with live accompaniment at the Cleveland Cinematheque, and once on a streaming channel at home. At home I fell asleep somewhere around one hour into it.

I also have problems with Red Dawn on many levels, but the salient reason for a sci fi marathon is that it’s not science fiction. I don’t know anything about Hero 6. A number of people have suggested Women in the Moon, but it is very long.

WOMAN IN THE MOON was actually Booked a couple of years ago. But, at around 3 hours (depending on the copy), it was set aside. The only 98 copy I could find was a bootleg public domain DVD. Not sure if Cleveland found something better.

Their schedule is odd, but, that's seems par for the course. From the sounds of it, they don't have the hardcore contingent that Boston or Columbus does who live and die with the event. And, few - any? - who are like me and stay up for the entire duration.

Here's what looks like the final list.

Responding to LA's comment. List odd? Yes.
As a 30 year attendee I can confirm that Cleveland has a hard core of attendees comprising somewhere around a third of the audience, similar in knowledge and interest to the core at Boston and Columbus.
Oddly students are not a huge percentage of the overall number. The audience definitely skews older.
I used to have a handle on who programmed. Now it seems to be by committee with student film society members having the final vote, with the projectionist (for 43 years) and the faculty adviser (for more than 20 years) providing knowledge and  thought.
The schedule always has two or three recent,  not necessarily great, movies. Then real consideration is used to pick another half of so of the schedule. Then they fill it out with arbitrarily chosen crap.
