My grandma told me that she saw a movie at around age 6 in which a big dinosaur rampaged through a city and picked up skyscrapers in its hand. For years she was afraid of “dinosawers”.

This would have been around 1933 or 1934 so NOT Godzilla which was my 1st guess.

Any ideas what film it was?

@janellecshane the lost world? It's earlier, but they bring a dinosaur to London https://m.imdb.com/title/tt0016039/

@Tattooed_Mummy hmm could be! This was rural Minnesota, maybe they sometimes played older movies. I’ll ask her!
