Unicorn Movies

Classic Movies Like I'm going to have to go over the names of these. I've picked the
most common, mostly because I don't remember any others that had unicorns
in them in a major role. Or a minor role, or any role. If anyone out
there can give me the name of a movie with unicorns and a plot summary I
can put it up here. If you can help me get the movie I'll be really happy.
Oh yes I will.
