Saw it around the end of 90's on TV. The most unique scene is when a man and a woman is travelling (seemingly in hurry/panic) with other travelers (they might be stranded) around them. The man is experienced with the method and warns her to not move too fast. He told about spending a long periods just to take his nose back. When he prevents her fall, he warns her to not laugh, and there's another scene where the laughing travelers explode. The method seems to be related to electricity: incandescent bulbs are shown prominently. One of the time periods they visit is at least before the computer era in crowded Chinese-looking city, when they are being chased and had to escape using the time travel method.
