The wrestling ring looked more like the set of an action movie Sunday night ... with a WWE superstar being LIT ON FIRE to end a highly-anticipated main event!!
And, just like a movie, the whole thing was not real and scripted ... but it was still insane to watch!!!
Bray Wyatt's "The Fiend" character was squaring off with Randy Orton in a "Firefly Funhouse Inferno" match -- where, in order to win, a wrestler has set the other on fire.
And, after several minutes of brawling ... Orton did just that to Wyatt!
