For some reasons, 1 vs 1 and 1 vs multi (>4) fight sequences are very common in martial art films history, however, 1 vs 2 long fight sequences are quite rare.

Do you know some cool 1 vs 2 fight in martial art films history?

I know some:

Final fight in So Close (2002): the villain old man vs Zhao Wei & Karen Mok. So Close 2002 wasn't an acclaimed film and box office success, however, its final fight is quite good in my opinion. (at first, the villain old man defeated Zhao Wei, then Karen Mok join the fight)

Mad Dog vs Rama(Iko) & his brother in The Raid: probably the best 1 vs 2 fight all time

Rama (Iko) vs Alicia Hammer girl & Baseball boy in The Raid 2

Yuda (Iko) vs 2 western men in Merantau (one western man killed first, the other western man defeated shortly after his death)
