As most of us know DN played a bad guy here but 2 yrs later he was in
THE BIG SHOW another circus film which had pretty much the same plot as House of Strangers/Broken Lance

In this 3rd film there's a daughter who David marries

The other circus film is of course GREATEST SHOW ON EARTH

All 3 films highlight the trapeze
