AceShowbiz - "Parasite" director Bong Joon Ho had to hide the identity of one of his stars while promoting the film, so as not to ruin the big twist.
Park Myung Hoon was forbidden from taking part in the movie's publicity tour, because his director wanted viewers to be surprised when his character appears.
Bong tells WENN, "It was so important to make sure that the second half of the film remained a secret, so we had all the actors and crew members sign an NDA (non-disclosure agreement) particularly from the part where the original housekeeper comes back and rings the doorbell."
"After that we made sure that none of that was revealed to the public and ever since Cannes we put in a lot of effort to keep that a secret. Particularly the actor, who is in the bunker, who plays the husband (of the housekeeper)."
"He went to the Cannes Film Festival, but had to remain hidden. Even with the premiere screening, he had to be in a dark corner on the second floor and had to leave five minutes before the film ended and before the standing ovation to avoid all the reporters, because his existence in itself is a spoiler. He had a hard time."
"Three weeks after the film was released we really focused on introducing him as part of the cast."
