Old 80s anime movie, Black Lion.
Modern battle tanks and aircraft against medieval Japanese infantry and cavalry, lead by Nobunaga Oda. Oh, and the mad cyborg samurai, Genai Doma. Killer of Ninjas, many many Ninjas. "Your head doesn't grow back after I tear it off!? This is too easy!"
And if that doesn't work for ya, go watch History of the World Part 1, one of Mel Brooks greatest comedies. Made sometime in the 70s, before censorship raped a lot of fun outta comedies.
