It Happened on Fifth Avenue (1947)
Every winter, Michael J. O’Connor, the second richest man in the world, leaves his 5th Avenue mansion for warmer climes. Every winter, Aloysius T. McKeever, homeless man, moves into the 5th Avenue mansion. This particular winter, McKeever meets Jim Bullock, an army veteran who has recently been evicted from his apartment and offers to share the mansion with him. It’s not long before the mansion has a few more guests, including: Jim’s army buddies and their wives and children; runaway heiress Trudy; and even Michael J. O’Connor, himself.
