Earliest Movie w/ Kung-Fu

What is the earliest english language movie with Kung-fu in it ?
My bet would be 1963's '55 days at Peking' that had a kick ass demo scene with 2 Chnese kung-fu practitioners performing barehand and with swords.

Wong fei hong?

I don't know about ones actually in english though

Nothing is to be feared, only understood....

When I was attending a community college in the early 1980s, there was an educational film about China that included actual film footage of some of the "boxers" training during the Boxer Rebellion in 1900. This footage was very brief, too fast and jerky, like all old film footage, and showed a guy with a que doing a broadsword form in a field with a crowd of other "boxers" around.
