Starts with man has machine that turns anything to gold. Throws gold coin in machine and Creature emerges covered in Coins. Creature proceeds on a rampage of killing and taking identities of those it slays. It has a mask that copies the slain persons face which Creature then uses to have that persons’ face. Does this several times. Men and women. One victim was a nurse. Detectives finally catch up to Creature and kill it. It is discovered (at end of film) Creature was pregnant.
I asked on the site I have mentioned and they reccomended Terror from the Year 5000. Could it be that film?
