Man in a trench coat (I think) has traveled to the future and is in a place that looks like a post apocalyptic Los Angeles. Lots of bombed out looking buildings, rubble, concrete, etc. He is there to fight some kind of mutant things, possibly robotic. I think one of the mutant robotic things looks like Krang from TMNT but on a floating disc thing, with little robotic arm things.
Details: Possibly 80’s/90s. I remember the color of the scene, everything had that blue tint that post apocalyptic movies sometimes do. I believe time travel was involved but possibly not. I don’t remember the hero. Some kind of rutger hauer type.
