The Doberman Gang

Here's the trailer for my dad's extremely silly (but successful) movie The Doberman Gang (1972). I remember seeing the movie in the theater when it first came out, and liking it a lot. (I must've been seven at the time!) It spawned two sequels, one starring Fred Astaire. After The Deer Hunter came out, I told my dad he ought to always put animals in the titles of his films, since they were so successful...
