I just watched When Worlds Collide (1951) for the first time since I was a kid. The model work is impressive but mostly, it's kind of dull -- not nearly as fun as It Came From Outer Space. But definitely well-made!

@tirebiter73 I suspected as much! And to be clear: I think I would have loved it at the time. But watching it now, it seems like it's mostly about a love triangle. At my age, I'm more into The Andromeda Strain and Phase IV. I think it provided the same kind of experience for viewers at the time. But no art works forever!
