I just had a memory out of nowhere of a movie scene I watched long ago, the movie scene as I remember went like this:
A giant grey/steel coloured (either it was wearing an exoskeleton or its skin colour was grey/steel) monster was running over the roof of houses trying to evade capture and at one point busted through a metal gate. Eventually the pursuers surround him and each pursuer whips out a leash with which they capture the monster/man in exoskeleton. The setting of the movie seemed old i.e the movie was not set in modern times maybe somewhere 1700's or 1800's maybe. Very vaguely but I think there was a scene set in a place like Venice (not exactly Venice) because the streets had water and buildings were around it.
As a kid I only watched Marvel cartoons and read Marvel comics and hence as a child when I watched it I initially considered the monster/man in exoskeleton as Iron Man or Grey Hulk because it was huge like Hulk or the original Iron Man suit, but it was certainly not a Marvel movie.
The movie was live action, in English. As for the science fiction elements, inclusion of a huge grey couloured/man in exoskeleton would suffice. I can't date the production year. I saw it around 2014-2015 on TV but the movie felt much older.
