Are you posting the next still, @KayinBlack? I love threads like this because I get to know about new (or old) movies I may like so I'm kinda itching
I'm going to have to revisit that film - I think I was too young when I watched it the first time around and didn't understand it properly. That head stuck with me though, for obvious reasons! Here's the next: I tried not to make it toooo easy, but I'm sure you'll have seen it. I have a couple of further clues just in case, but it IS a main part of the film though.
Somehow Krull just seemed a logical follow-on to Zardoz ... Here ya go : (hint : It's a Sci-Fi flick)
I think it's going to be a swing and a miss for me, but I'll still go for it... Total Recall (original)
