Hello, i remember this scene from the childhood, its a scene of movie monsters of the 50s, everyone was fleeing through the streets except a woman with skirt caught in car door, she was tugging at her skirt to free herself, but fails and the camera gets closer and closer as she stops trying to escape and screams
Well, it's been 3 weeks since this was posted and I don't know if the OP will be back, but the answer to this question is Earth vs The Spider aka The Spider, from 1958. The scene in question occurs when the giant spider rampages through town.
