Who helped Jackie Chan become famous?

Answer 1

In Hong Kong it was Ng See Yuen of Seasonal Films who borrowed Jackie Chan from Lo Wei to make 2 films - Snake in the Eagles Shadow and Drunken Master - and director for the two films Yuen Woo Ping - who gave Jackie the opportunity to develop his own style.
