It was Francis Ford Coppolla's Goodburger.

Actually that fight inspired Rocky. Not the "Great White Hype"
BTW: Good Burger was directed by Brian Robbins. He later went on to direct hits like "Norbit" and "Hardball" (I cried when G Baby got shot)

Not compared to most modern heavyweight fights, especially in the final round

These guys had been beating the shit out of each other all night, and that was late-period Ali in full seek and destroy mode, I'm surprised the guy lasted that long. They threw a lot of punches.

Dude, oogaBooga goes fourteen rounds with Ali like twice before breakfast alone.

Seriously. Compared with most MMA fights, this is downright satisfying, especially Wepner getting Ali in the face.

uh, as opposed to a hard KO in the 3rd round of an mma fight?

MMA is not good for your brain or body, either.
