Harvards disguised as Zero fighters appeared in the film The Final Countdown, and on TV the same types appeared in Black Sheep Squadron and at least one episode of Fantasy Island, plus also Tales of the Gold Monkey.

I’m sure a Harvard appeared playing a Zero in the film The Flying Leathernecks, along with Hellcats playing Zeroes. And wasn’t it Harvards in the Pearl Harbor attack scenes of From Here To Eternity?

Harvards also appeared in The Tuskegee Airmen

I dunno about The Flying Leathernecks, but you’re spot on about the Hellcats playing Zeros.

I’m sure a Harvard appeard in an episode of Star Trek once, too.
And yes, it had Japanese meatballs on it!
