This is not restricted to the film world.
Who are the performers whose real-life persona interferes with your ability to enjoy their work? Reasons of course may vary: Maybe you saw an interview in which the person(s) made racist comments or was(were) simply an ass, or maybe they have politics that are in radical opposition to your own, or maybe you have “insider info” on some of their backstage behaviour.
Example: I can not watch any Jean Claude Van Damme movie without thinking “You egotisical a**hole!” every time his face is on the screen. I find him totally unbelievable as a sympathetic character of any kind, especially if he tries to play the “nice guy”. I can not enjoy his movies as a result. (Not that they are particularly well-crafted oeuvres from the start.)
I’ve seen him be a blatantly egotistical twit in many interviews and I’ve had friends who’ve had to work with him.
It is customary at the end of a shoot, to have a “wrap party” and typically the higher-ups give the crew small gifts as tokens of appreciation – a materialistic way of saying “good job.” Depending on where you stand on the food chain, the quality of your gift may vary. Crew members will often get baseball caps, jackets, maybe a nice (but not overly expensive) watch. JCVD crew gift? He gave the crew autographed pictures of himself.
