BHWW Pffffft, my hall of mirrors is sooooo much nicer than that one.
He gets his Bruce Lee noises going and then he justs jumps, not even trying to kick or nothing, he just jumps.
Riskbreaker Most people hearing Bruce screaming would had duck in fear, guess the plan didn't worked this time.
But in all seriousness, the only reason to explain that scene is that it was a combination of crappy direction and coreography not working right. The movie is fun, but it is clear that without Bruce this would be just some forgotten b-movie with Jim Kelly and Bolo looking mean.
