A Better Tomorrow (; lit. "Invincible") is a 2010 South Korean contemporary gangster drama film, starring Joo Jin-mo, Song Seung-heon, Kim Kang-woo and Jo Han-sun. It is an official remake of the 1986 Hong Kong film "A Better Tomorrow". It was directed by Song Hae-sung and produced by Fingerprint Pictures. John Woo, who directed the original 1986 version, acted as executive producer.
John Woo has met Joo jin-mo
The context does not explicitly state that the exec producer and the star actor have met in person; it is not extremely unbelievable that an executive producer might work from a studio office and never actually visit the set itself
