If it's Segal, then yes, all the stories you have heard are true, and there are probably worse ones that you don't know of. The guy is a terrible sack of shit and you will be badgered into sexual favours, harassed until you quit or just outright fired. You want nothing to do with the man. He's an abusive, narcissistic deviant pretending to be a buddhist.
If it's Van Damme, alls the stories you have heard are true, but he's more of a drug addict than a sexual predator. Not to say he won't try to sleep with you, though. Also, he gave Natasha Henstridge the clap, so keep that in mind.
PM me if you don't want to say the actor's name in public and I'll respond if I have any inside knowledge.
